Tear half of a baguette in bite size pieces into a buttered pan
Drench the bread in dry white wine
Top with onions and ham
Sprinkle generously with grated guyere cheese
Pop into a hot oven for 30 minutes until the cheesy is gooey and bubbling.
Of course, I don’t do onions, so I had to find something else. Decided on artichoke hearts and roasted red peppers. You could use anything really--sun dried tomatoes, herbs, olives, leeks, garlic (fresh or roasted), capers, mushrooms.
Use different leftover meats and a variety of melty cheeses. I’m thinking fontina, gouda, mozzarella, provolone, havarti, asiago….
