French bread loaf brushed with roasted garlic butter, filled with thinly sliced ribeye steak, caramelized sweet onions, roasted poblano peppers, shredded Oaxaca cheese, and provolone slices, then grilled or baked until the cheese melts into gooey perfection
Ask butcher to shave ribeye thinly for authentic texture
Can substitute mozzarella for Oaxaca cheese
Roast poblanos over direct flame first for smokier flavor
Extra garlic butter makes excellent dipping sauce
Assemble ahead and refrigerate up to 4 hours before cooking
Leftover slices reheat well in 350°F oven for 10 minutes
For spicier version, add jalapeños or use pepper jack cheese
Bell peppers can substitute for poblanos if preferred
