  • Since the ground beef is not browned ahead of time, use a lean ratio of ground beef in this recipe.

Recipe Variations

  • Substitute 1 cup of uncooked white or brown Minute Rice for the cooked rice.
  • Instead of ground beef, use ground turkey in the filling.
  • Substitute a 14 1/2-ounce can of diced tomatoes and a 10 3/4-ounce can of condensed tomato soup for the spaghetti sauce. Combine the two in a bowl and pour over the peppers.
  • Chop the tops of the peppers finely and add them to the filling or to the sauce mixture.
  • Instead of plain white rice, add cooked Mexican or Spanish rice to the beef mixture. Use Uncle Ben's Ready Rice or Rice-a-Roni brand.
  • For Tex-Mex or Mexican flavors, substitute two 14 1/2-ounce cans of chili-style or Mexican style tomatoes for the spaghetti sauce.
