Directions
1. Preheat oven to 400°F.
2. To caramelize onions, add butter to pan and turn on medium heat. Once butter is melted add onions. Keep onions covered and cook until golden brown about 12-15 minutes (stir occasionally.)
3. While onions are cooking, brown ground beef in olive oil. After meat is brown drain grease. Fold in cheese, and caramelized onions. Add salt and pepper to taste.
4. Unroll refrigerated Danish Pastry Dough on enclosed parchment paper and place on a baking sheet. Cut the dough sheet in 6 evenly shaped triangles by cutting it in 3 same sized rectangulars (top to bottom) and then 3 times diagonally. Add mixture to the inside of wide end of croissant and roll, sealing edges. Brush with egg wash and sprinkle with sesame seeds.
5. Bake for 15 minutes or until golden brown. While Croissant Burger Bites are baking, make the dipping sauce by combining relish, mayo and ketchup. Serve warm with dipping sauce.
