For a vegetarian twist, substitute ground beef with quinoa or tofu.
To spice it up, add diced jalapeños to the beef and rice mixture.
Opt for mixed colored bell peppers for a visually appealing dish.
For cheese lovers, mix in some cheese with the beef and rice filling too.
If the peppers don’t stand upright in the baking dish, slice a tiny bit off the bottom to make a flat base.
