Grilled Ham and Gouda Sandwiches with Frisee and Caramelized Onions

This is an easy and tasty sandwich from Bon Appetit that takes some time because of the onions, but it is so worth it.

Remember to ask the deli counter to slice the Gouda cheese, it takes too much effort to slice them thinly. You can use other cheeses too, but Gouda gives it a great taste with the frisee.

Of course I made some changes:)

I added tomatoes, which made it yummier:)

I had to add some Dijon mustard, just because there is ham in the sandwich:)

And I used my panini maker instead of using the skillet to cook the sandwiches. They came out just great.

GRILLED HAM AND GOUDA SANDWICHES WITH FRISEE AND CARAMELIZED ONIONS

Ingredients:
1 tablespoon extra-virgin olive oil
1 large onion, thinly sliced
Unsalted butter, room temperature
4 1/3-inch-thick slices country white bread or sourdough bread
4 ounces thinly sliced smoked ham, divided
3 ounces Gouda cheese, thinly sliced, divided
2 large handfuls frisée, torn into bite-size pieces (about 1 cup), divided

Directions:
Heat oil in large nonstick skillet over medium heat. Add onion; sauté 5 minutes. Reduce heat to medium-low; cover and cook until onion is very tender and golden, stirring frequently, about 25 minutes longer. Season with salt and pepper. Cool slightly.

Butter 2 bread slices. Place bread, buttered side down, on platter. Divide onion, ham, cheese, and frisée between bread slices. Top each with another bread slice; butter top slices.

Heat another large nonstick skillet over medium heat. Add sandwiches and cook until bread is golden brown and cheese melts, pressing occasionally with spatula, about 4 minutes per side. Cut sandwiches in half diagonally and serve immediately.

Makes 2 servings.
