We make chicken quesadillas on our griddle. I use the precooked chicken strips, cheese, onions, jalapenos. Those are very quick and pretty good. I heat up a cheese dip in the microwave and have chips, dip, salsa, and the quesadillas. For dessert, we make a sweet quesadilla with peanut butter, marshmallows, and chocolate chips.
Of course, all the old standbys of spaghetti, tacos, and sloppy joes work. I will brown all the meat ahead of time, freeze it and then use when needed. I like to use the crockpot when I can because it saves time.
