This savory veggie panini with caramelized onions makes the vegetarian lifestyle easy. The fontina cheese oozes out of the sandwich, the bread is warm and crispy, and the sautéed kale adds a complementary lightness.
Assemble your sandwiches! Spread 1 clove of roasted garlic on one side of the sandwich. Top with 1 oz fontina cheese per sandwich, 1/4 of the caramelized onion mixture, 1/4 of the kale, and a dash of salt/pepper to taste.
