Bell pepper substitute?
I love stir-fries and tex mex dishes, but bell peppers (green red and yellow) give me bad indigestion. Onions too but to a lesser degree. Any ideas on what I can substitute in Chinese/mexican style dishes for these veggies? I use french-cut green beans a lot to replace the green bell peppers, wondering what else would give me the nice colors of peppers but without the tummy troubles.
