This is one of my favorite lazy bachelor recipes. It makes enough to keep me from having to cook for a week or so. In fact, not only does it make good leftovers, it actually improves with age - so much so that I generally make it a day ahead of when I want to start using it.
Sweet bell peppers are perhaps the least common form of the pepper family found in Thailand, although they are readily available. They appear in some stir-fries and spicy salads but usually only in restaurants catering to westerners. Bell peppers are in the same capsicum family as hot chilies. Just one gene makes the difference between hot and mild peppers.
