Prepare your biscuits by flattening them between your hands. In a muffin tin, place the flattened biscuits in a muffin cavity, making sure to push the biscuit dough down and shaping around the sides. It should be perfectly formed to the muffin cavity. Do the same with the rest of the biscuits. Set aside.

In a medium-sized skillet, add in the ground beef, minced garlic, salt and pepper. Cook until the beef in cooked all the way through, then add in the frozen vegetables.

In a small bowl, whisk together the flour and beef stock, making sure there are no clumps. Whisk into the ground beef mixture and allow it to simmer on medium-to-low heat for at least 10 minutes. The mixture should thicken. Preheat oven to 350 degree.

Pour the ground beef mixture on top of the biscuits (1 tablespoon for each muffin cavity), then top with mashed potatoes. Bake for 20 minutes, or until the biscuits are browned.
