1/2 cup roasted red peppers (4 ounces), finely chopped
1/2 cup marinated artichokes (4 ounces), drained and finely chopped
2 pickled jalapeños, seeded and thinly sliced
Brush the bread with the olive oil and arrange, oiled side down, on a work surface. Top half of the slices with the Fontina, red peppers, artichokes and pickled jalapeños. Close the sandwiches.
Preheat a skillet or panini press. Grill the sandwiches over low heat until the bread is toasted and the cheese is melted, 10 minutes. If using a skillet, press the sandwiches with a spatula and flip them halfway through. Cut in half and serve right away.
