Preheat a grill.
Brush the outside of the mushrooms with olive oil and sprinkle all over with the rub.
In a saute pan, brown the burger and sausage meat. Add the onion, bell pepper, and garlic and cook until soft. Drain excess fat. Mix the remaining ingredients in a large bowl and add the drained meat. Season with salt and pepper, to taste, and mix well.
Spoon the mixture into mushrooms and grill until mushrooms are tender.
