To prepare a turkey veggie meatloaf cups recipe, first you will need to prepare the turkey. You can use any type of meat, but turkey is my favorite. I like to use turkey because it's so flavorful, and the texture is so moist and tender. If you don't have turkey, you can also use ham, pork, chicken, or beef. Place all of the ingredients except the peppers and green onions in the large bowl. Pour the vegetable broth over the meat mixture and stir to combine. Cover the bowl with plastic wrap and refrigerate for at least 1 hour or overnight. When you're ready to cook, take out the cups from the refrigerator and place them on the rimmed baking sheet. Bake for 20 to 25 minutes or until the tops are golden brown. Remove from oven and let stand for 5 to 10 minutes before slicing and serving.
