Heat oven to 400°. Lightly spray 10 muffin cups with baking spray or grease lightly.
Flatten biscuits slightly and press into muffin cups, pressing up the sides. Put about 1/2 teaspoon of the barbecue sauce in each cup. Top with about 1 to 1 1/2 tablespoons of pulled pork, then top with a thin slice of tomato and a pickle. Sprinkle with a little onion and then top each cup with shredded cheese. Bake for 12 to 14 minutes, until lightly browned.
Makes 5 to 10 servings, depending on the meal and appetites.
