Take your pick! Grilled Cheese or Cheese Quesadilla. They’re practically the same thing just from different regions; flour product with cheese, only I didn’t use butter on the quesadillas. These are two of the easiest, kid-favorite foods to make.
Buttered sourdough bread, butter side down on a medium to medium-high skillet, cover with cheese (really whatever you have in the fridge is worth a try), cover with another slice of buttered bread, butter side up. When the cheese begins to melt, use a spatula and flip the entire sandwich over and heat until the bread is a toasted golden brown.
Same thing with the quesadilla, just minus the butter. Warm the tortilla covered in cheese and a second tortilla on a dry skillet. When the cheese melts, flip it over to warm the other tortilla (or you can skip the second tortilla and when the cheese melts, fold it in half and serve. I added cooked, shredded chicken and salt and pepper to mine to make it fancy (for grown-ups or older kids who have a more developed palate).
What you need per person:
2 slices of bread or 2 flour tortillas
½ cup cheese
2 tablespoons of butter (for bread only)
