Preheat oven to 400°, wash, then cut 2 peppers in half lengthwise + discard seeds; lay cut-side up in lightly oiled baking dish, season with salt/pep + bake 15-20 min until tender

Meanwhile, heat 1 tsp oil in skillet over med-high; add half the beef to pan, break into large chunks + sear undisturbed 2 min; flip meat over, season with salt/pep, then break into small pieces; cook 2-3 min until fully cooked + no pinkness remains; remove from heat + mix in ½ cup sauce

Divide meat among peppers + top each with 1-2 tbsp cheese; bake 10-15 min more or until hot + melty

Tip: save instructions to cook remaining meat tomorrow or wrap tightly + freeze
