I have a friend that’s a supertaster 🙁 I’m so sorry!
I use a lot of spices to make things taste “better”. (I don’t mind plain veggies, but I get bored.) Some things I like are curry, garlic, and pesto (easy to make your own with basil, garlic, olive oil).
I don’t know if those will set off your supertaste or not.
You might just have to learn to like them.
Oh, also, blended zucchini soup, to me anyway, tastes like corn soup.
