In large dutch oven on stove, brown meat over medium heat in oil; drain. Sprinkle onions over meat; combine tomato sauce, picante sauce, cumin, oregano and garlic; pour over meat and onions. Reduce heat, cover and simmer gently about 2 to 2 1/2 hours, adding green pepper during last 15 minutes of cooking. Remove meat to serving plate; keep warm. Bring sauce in pan to boil, stirring frequently until sauce is thickened (about 5 minutes). Skim fat from sauce; serve sauce and additional picante sauce with meat. On busy days, I just empty everything into the crockpot and let it cook on low for 6-8 hours!
