Mexican Adobo Beef

Heat oil in a large nonstick skillet on medium-high. Add steak, onion, seasoning, and cinnamon; sauté just until outside surface is no longer pink, about 5 min

Remove meat from pan; set aside. Add tomato sauce, orange juice, and vinegar to the pan. Reduce heat to medium and cook, stirring, until sauce thickens, about 5 min

Return meat to pan; reheat 1 min. Serve immediately
