Preheat the oven to 400 degrees and line a baking dish with parchment paper.
On a medium pan or skillet, saute onions and garlic in olive oil over medium heat. Add in cooked brown rice, Italian seasoning, black beans, and tomatoes and saute for 5-8 minutes.
Cut the bell pepper tops off, about 1 inch from top and carve the peppers into a pumpkin face.
Stuff the bell peppers with the rice mixture until ¾ full.
Place the bell peppers on a narrow baking tray, so they stand up right.
Cook for 10 minutes, so the pepper is slightly cooked, then ENJOY!
