Apple Grilled Cheese

• 8 slices sourdough bread
• 4 slices sharp cheddar cheese
• 1 cup full-fat mozzarella cheese (¼ cup per sandwich)
• 4 tbsp maple bacon onion jam (such as Stonewall Kitchen)
• ¼ cup prewashed baby spinach leaves, divided
• 1 large North Bay Honeycrisp apple, cored and sliced
• ½ cup regular mayonnaise

In a non-stick pan or griddle over medium heat, place a slice of bread spread with mayo, mayo side down, on the pan. Layer ingredients; start with jam, mozzarella cheese, cheddar cheese, apple slices, and spinach. Top with another slice of bread and spread a layer of mayo on top. Repeat with the remaining three sandwiches. Fry the sandwiches over medium-to-medium-low heat until the bottoms are browned and the cheese starts to melt. Carefully flip each sandwich over and cook until golden brown, the cheese is melted, and the filling is warm. Remove from heat and let sit for a minute or two to set up before cutting in half and serving.
