This grilled cheese has classic Italian salami, provolone and onions with the updated twist of apples and arugula.
If you don’t already have the pickled red onions in the refrigerator then make them first thing. We recommend making extra and keeping this versatile condiment on hand at all times.
Wash and dry the apple and arugula. Slice the apple into large, thin circles.
Spread mayonnaise on both sides of the bread. You don’t much on the side of bread that will be touching the hot pan. It’s more for helping the bread get golden, whereas the mayonnaise on the inside of the bread is for flavor and moisture.
Place bread in hot pan over medium-low to low heat, ideally you should use a griddle without any sides so that you don’t burn your hands since you will be building the sandwich inside the pan.
Add a handful, about ¼ cup, of arugula, then slices of apple, pickled red onion, 2 slices of cheese, top with another piece of bread with mayonnaise on both sides.
Cover and cook until bread is golden, flip and continue to cook until other side of bread is golden and cheese is melted. This is why you only use medium-low to low heat so that you get the ooey gooey melted cheese!
Remove from pan and let sit for a couple of minutes to set up. Slice in half and serve with a green salad and cookie for dessert.
Bring all ingredients to a boil in a saucepan. Once boiling take off the heat and cover until onions are room temperature. You can use the hot onions right away. Or make the night before and let sit covered in your refrigerator to meld the flavors. Onions will keep this way for about 2 months. You will have quite a bit extra, see our post on pickled red onions for other uses.
