This will make 15 appetizers if you separate each biscuit into 3 sections. So you'll need to use two 12-count muffin tins or cook three of them in 2 batches.
Spray muffin tins with non-stick spray. Preheat oven to 350 degrees F.
Separate biscuits into 3 thinner rounds. Don't cut them, you will pull them apart, this is why getting the biscuits with layers is important.
Brown sausage and drain excess grease. Add diced tomatoes and cream cheese. Stir until heated through and cream cheese is melted. Allow to cool slightly
Press one biscuit layer into pan forming cups.
Fill each wonton cup with 1-2 tablespoons of the sausage mixture.
Cook at 350 12 to 13 minutes or until hot and bubbly.
Serve warm or at room temperature. Store in an airtight container in the refrigerator.
