What vegetable for sauteed zucchini could I use instead of tomatoes? I like to fry or sautee onions, garlic, chilis, spices (for flavor) and zucchini (the main ingredient); then stir them in a can of chopped tomatoes and simmer for a few minutes. The tomatoes are a way to add a sauce with some thickness that brings all the ingredients together. I want to get close to the texture and consistency, but I'm looking for something else so the dish does not always taste the same.

Is there another vegetable or fruit I could use instead of the tomatoes?
You could use coconut milk and curry-type flavorings (e.g. coriander, cumin, turmeric, galangal, ginger, lemongrass, any type of chili pepper, cilantro), for a very different taste with a somewhat similar texture.
