Multi use stuff. Hamburger buns can be used for chicken sandwiches, sloppy joes, and burgers. Tortillas for quesadillas and chili, and burritos.
Premake sloppy joe meat, unfreeze, add some cheddar cheese, a side of fresh fruit, and you are good to go.
Same with chicken breasts. Cook a dozen or so, then you can unfreeze and use for a fresh salad, chop for chicken salad and quesadillas or use whole on a chicken sandwich.
Make some marinara sauce, freeze it, and use it with pasta and fresh shrimp from the Coast.
All pretty easy and fast.
Have a great trip.... Don't forget to let the hubby share the cooking on the bbq!
