Spicy Stuffed Peppers

Eric and I made these tonight for dinner. They were so tasty and super simple.

8 med bell peppers, red or green
2 med onions, chopped
2 lbs ground beef
2-3 tomatoes, 2-3" diameter, chopped
1 taco sauce mix packet - We used the kind you find at Safeway with the small packages of dried chiles and other Mexican spices. It's just spices, no fillers or starches
1/2- whole habenero chile, chopped very small
1 1/2 c grated cheese - We used half jack & half sharp cheddar

Preheat oven to 400 degrees F. Line 9 x 13 pan with foil.
Brown the beef with the onions. Add tomatoes, flavor packet and 1/3 cup water and cook 3-5 minutes. Salt and pepper to taste. Add chile pepper, cook 2 minutes.
Cut tops off of peppers and remove seeds and ribs and place in foil-lined pan. Fill peppers with meat filling. Bake 30 minutes. Sprinkle cheese on top of peppers and bake until melted.
Serve with sour cream and guacamole.
