Simply Scrumptious Sandwich

This is a super simple recipe, but when Adam and I ate it, we could not get enough. Perfect for a night when you just don't have the energy to cook or when you want an extra scrumptious lunch.

Grilled Smoked-Gouda Sandwich with Mustard Dipping Sauce (Vegetarian Planet, Didi Emmons)

1 tsp. Dijon mustard
1 tsp. honey
2 Tbs. plain whole, low-fat, or nonfat sour cream
3 oz. smoked Gouda cheese, sliced thin
4 slices bread (I like to use large slices of rye bread)
1 tomato, sliced thin
a small amount of thinly sliced onion
2 Tbs. olive oil

1. Make the dipping sauce: Stir together the mustard and the honey in a small bowl. Add the sour cream, and spoon the sauce into two dipping bowls.
2. Lay the cheese slices on two pieces of the bread, place the tomato slices on top of the cheese, and then top with as much onion as you'd like. Place the other two pieces of bread on top of the first two.
3. Heat the olive oil in a large skillet over medium heat. Place the two sandwiches in the skillet, and weigh down the sandwiches with either a sandwich press or another skillet. Reduce the heat to low. Pan-fry the sandwiches until they are golden on the bottom, about 3 minutes, then flip them. Continue to cook until the cheese is melting and the other side is golden. Cut the sandwiches in half, and serve them with the dipping sauce.
