You can store the rice salad stuffed tomatoes in the fridge in an airtight container for two days.

You can prepare the rice salad in advance and use it at the last moment to fill the tomatoes.

You can enrich the filling with many other ingredients such as corn, diced vegetables, or pickled vegetables like zucchini, peppers, eggplants, ham cubes, smoked salmon, etc.
