For the shrimp, I used 2 bags of Walmart brand, frozen, cooked, large, peeled, deveined, tail on shrimp. I thawed them, removed the tails, and chopped them. This was just a bit over 3 cups, each bag was 12 oz / 340 g.
Cut the tops off the peppers, remove seeds and membrane.
Place the peppers in small amount of boiling salted water, cover, and steam for 5 minutes, drain. Sprinkle insides with salt.
Preheat your oven to 180° C (350° F), get out a 7x11 inch baking pan.
In a mixing bowl, add remaining ingredients except the tomato sauce. Mix together and season with salt and pepper as desired.
Fill peppers and place upright in the baking pan. Spoon the tomato sauce around the peppers.
Bake for 30 minutes.
Place peppers on a serving plate, spoon sauce over them, serve and enjoy.
