Preheat a grill to medium high and oil the grates. Place the ground beef in a medium mixing bowl. Add 1 1/2 teaspoons salt and 3/4 teaspoon pepper. Add a few dashes of Tabasco sauce, then with your hands, mix the meat and seasoning well.
Form the meat into six 1-inch-thick patties and place on the grill. Cover and cook 3 minutes, then rotate, leaving them on the same side, and cook 3 more minutes. Flip and repeat on the other side.
Meanwhile, slice the rolls in half and spread each cut side with 1/2 tablespoon butter. Grill the rolls, cut-side down, until lightly toasted. Build the burgers with assorted toppings.
Melt 2 tablespoons butter in a large skillet over medium-high heat; add 1 pound sliced mushrooms, season with salt and pepper and cook 2 minutes. Add 2 to 3 tablespoons broth or wine and cook 6 to 8 more minutes.
Melt 4 tablespoons butter in a skillet over low heat. Add 2 large sliced red onions and 3 to 4 tablespoons brown sugar. Cook until caramelized, tossing occasionally, about 20 minutes.
