We used a beef sirloin for this meal. Also mushrooms, snap peas, red pepper, and onions.The secret to tender lean beef, is to let it simmer in the marinade sauce.
We seasoned and browned the meat. remove to a plate, then saute the onions peppers and snap peas. Mushrooms don't take as long, so we did them in a separate pan. Then add all ingredients to same pan, add marinade, we used orange juice, teriyaki sauce, and some cornstarch for thickening, and cover and simmer for 20 minutes.
