Rice and lentils make a steady meal prep base, but they can feel too heavy if nothing fresh comes in at the end. Tomatoes and lemon are the part that makes the bowl taste alive. The trick is not to remove them. The trick is to keep them from soaking into the rice too early.

The good part should not ruin the base
A bowl made only for storage can become too careful. Plain rice, plain lentils, dry vegetables and no juicy finish may hold up well, but it does not always make a lunch you actually want to eat the next day. A good meal prep bowl needs flavor, not just structure.
Tomatoes and lemon solve that problem quickly. Cherry tomatoes bring juice and sweetness. Lemon brings sharpness. Herbs make the whole bowl feel less heavy. Together, they turn rice and lentils from a useful base into a lunch that still feels fresh.
But they also bring the risk.
If chopped tomatoes, lemon juice and salt sit directly on rice overnight, the grains can absorb too much liquid. The lentils can lose their clean texture. By the next day, the bowl may still be safe and edible, but it can taste flat, wet and tired.
That is why this bowl keeps two jobs separate. The rice and lentils are the meal prep base. The tomato lemon mixture is the fresh finish.
Start with rice that is not too soft. Brown rice, basmati rice or long-grain white rice all work, but the grains should stay separate enough to hold their shape. If the rice is already sticky or wet before it goes into the container, the tomato topping will only make that problem worse later.
Use green, brown or black lentils if you can. They hold their shape better than red lentils, which are better for soups, stews or soft spreads. The lentils should be tender, but not collapsing. Once drained, let them cool before mixing them with the rice.
For the base, keep the seasoning simple: olive oil, a little salt, black pepper, lemon zest and chopped parsley. Lemon zest is useful because it gives lemon flavor without adding much liquid. Save most of the lemon juice for the topping or for the day you eat.
This is the same kind of practical separation that helps in a good meal prep bowl components storage chart. The question is not only what tastes good together. It is also what should touch what before lunch.
For 3 meal prep bowls, use about 3 cups cooked rice and 2 cups cooked lentils. Mix them with 1 tablespoon olive oil, lemon zest, black pepper and a small handful of chopped parsley. Divide this base into containers and let it cool fully before closing the lids.
Now make the part that keeps the bowl bright.
Use cherry tomatoes or grape tomatoes because they stay neater than large chopped tomatoes. If you are eating the bowl the same day, you can halve them right away. If you are prepping for tomorrow or the day after, leave some of them whole or keep the chopped tomatoes in a small separate container.
Add lemon juice, a little olive oil, parsley or mint, and a small pinch of salt only when you are close to eating. Salt pulls juice from tomatoes quickly, which is great when you want a quick fresh topping, but not great when that juice sits on rice overnight.
If you want more flavor, add a small amount of red onion, feta or olives. Keep them controlled. The tomatoes and lemon already do the main work here. Too many strong ingredients can make the bowl taste crowded by the second day.
A good way to pack this bowl is simple:
Put the rice and lentil base in the main container. Keep the tomato lemon topping in a small cup or on one side if you will eat it soon. Add herbs separately if they are delicate. Add lemon juice at lunch, or keep a wedge of lemon in the box and squeeze it over the bowl before eating.
This keeps the flavor fresh without asking the base to survive under liquid for two days.
For day one, you can eat the bowl cold, room temperature or gently warmed. If you warm the rice and lentils, add the tomatoes after heating, not before. Warm tomatoes can be delicious, but this particular bowl works better when the tomato lemon topping stays fresh and bright.
For day two, the same rule matters even more. Open the container, loosen the rice and lentils with a fork, then add the tomato lemon topping. If the base tastes a little muted, add a small squeeze of lemon and a few fresh herbs. That small finish often does more than adding another heavy sauce.
This bowl also works well with cucumber, but only if the cucumber stays separate. Cucumber can make the bowl feel cooler, yet it releases water fast once chopped and salted. If you add it, treat it like the tomatoes: fresh topping, not buried ingredient.
The best version is not the driest version. The best version is the one where the juicy part is still juicy when you want it, not when the rice has already absorbed it overnight.

These tomato lemon rice and lentil bowls are not trying to remove risk by removing flavor. They keep the steady part steady and the fresh part fresh. That is what makes the bowl feel good on day two: not just rice and lentils that survived the fridge, but tomatoes and lemon added when they can still do their job.
