You could maybe use them as a rub or marinade for either chicken or pork. If they are super spicy, maybe mix them with lemon or lime juice first.
I googled them and found this recipe for the yellow hot pepper paste: Aji Amarillo Avocado Tostada
. It looks like the calories might be okay if you cut back on the olive oil, reduced the amount of avocado, and didn't bother frying the tortilla. Try googling both of them; I found some other recipes, but they are all in spanish (you could try Google's translation).
Maybe go back to the grocer and ask him for suggestions? That's probably what I would do.
