Instant Pot filled peppers are easy and quick to make. Some like to cook the meat ahead, but I like to put all the ingredients in one pepper.
Sauce
You can pick a variety of bell peppers. Red taste sweeter and yellow is a in between sweet and bitter, but green one has a slightly bitter taste. All three colors will give you a different taste profile.
