While the onions are carmelizing, add the ground venison to the skillet the bacon was cooked in and cook until brown over medium-high heat. If you need to add more fat to the pan, use about 2 to 3 tablespoons EVOO. While the meat is browning, break it up into small pieces so it is easy to fill the holiday popovers. After the meat is browned, season it with salt and freshly ground black pepper, then remove to the same platter along with the bacon and reserve.
Once the onion and garlic are nice and caramel in color, add the pepper, tomatoes, salt and freshly ground black pepper cook until peppers are soft, 5 minutes.
After the onion, pepper, tomato mixture has softened, add in the reserved bacon and browned venison. Sprinkle the mixture with flour then add the stock, let the mixture cook for a 2-3 minutes to cook out the flour taste and thicken up the gravy a bit. Remove from heat and fold in 1/4 cup Asiago cheese and 1/4 cup provolone.
Remove the biscuits from the canister -- you will have a total of 16 each -- and slice each of them down the middle so you have 2 thin biscuits that are equal in size. Repeat this procedure to all the biscuits so that you have 32 thin biscuit rounds.
Line the muffin tin with 1 biscuit per muffin cup so it makes a little bowl then fill them with 1 1/2 to 2 tablespoons of filling. Repeat with the remaining muffin cups and sprinkle the remaining Asiago and provolone on top of each popover. Bake for 20-25 minutes until puffed and golden brown, and cooked through.
