Add 2 tablespoon of oil to a saut pan. Add the onion and pepper strips. Saut until the onion is tender. Remove from pan and set aside.

Heat the remaining oil in the pan. Drain the beef and add to the pan. Saut quickly to brown the beef, add the onions - peppers back to the pan. Stir fry for 1 minute more.
