Storage Tips
Store leftovers in an airtight container in the fridge for up to three days. Reheat gently in the oven covered with foil to avoid drying out the filling. You can freeze fully baked stuffed peppers individually wrapped for up to two months. Defrost overnight in the refrigerator before reheating.
Ingredient Substitutions
For a vegetarian version try black beans or sautéed mushrooms in place of beef. Cooked quinoa makes an excellent substitute for brown rice. If you do not have teriyaki sauce you can use a mix of soy sauce maple syrup and a splash of rice vinegar for a similar flavor.

A simple green salad or sliced cucumber tossed in rice vinegar is the ideal fresh side. Roasted sweet potatoes or cauliflower rice pair nicely with the sweet and savory flavors. For extra crunch serve with a handful of slivered almonds on top.
