Fresh fruits and vegetables are kosher year round and kosher for Pesach. I don’t even try to do the fake cakes and pastries and as a result I actually eat more healthily on Pesach than during the rest of the meal.
Here is one recipe, from *Indian-Jewish Cooking* by Mavis Hyman:
“Kuccha” Tomato salad
Cut tomatoes up into small pieces.
Add finely chopped scallions and cilantro (coriander — fresh is best but dried leaves work well, too).
Add salt and lemon juice.
Mix and serve.
Delicious.
