In a skillet, heat oil over medium high heat. Add the onion, bell peppers, and garlic. Cook for a few minutes till fragrant and beginning to wilt, then turn on low till wilted, about 10 minutes. Set aside.
In a large mixing bowl, add the meats, and remaining ingredients. Mix well. Add sauteed vegetables and mix well again. Shape into a long oval-ish blimp—resembling a fat loaf of French bread–and bake at 375 degrees in a baking pan, for approximately 45 minutes.
Serve with garlic mashed potatoes, (generously add some garlic powder when mashing the potatoes) and steamed broccoli. Enjoy!
