Preparation
Preheat oven to 250°F. Plug in waffle maker.
In a large skillet over medium-high heat, add oil. Brown burger about 5-6 minutes, add chopped onion and cook another 3-4 minutes. Once browned, add Worcestershire sauce, beef bouillon, garlic clove, salt and pepper. Turn heat off and let cool a bit.
While burger mixture is cooling, mix together waffle mix, milk, egg, and the second tablespoon EVOO. Add cooled burger mixture and half cup of Provolone cheese.
Brush the hot waffle maker with melted butter, spoon about ¼ cup of batter into center of each waffle. Close lid and cook until the waffles are golden brown and release from the waffle griddle cleanly.
