Simple Peas

Five ingredients. Olive oil (1) and butter (2), heated (about a tblsp. of each). One onion (3), diced. Cook the onions until they start to brown. Add a bag of frozen peas (4). Heat through. A little salt (5) at the end. We serve these a lot as a side, but I swear I can (and do) eat a big bowl of these all by themselves. Simple dish, simple post.
