I do the same - but I make a turkey chili instead of beef. I freeze single servings in zip loc baggies. One thing I make is basic ramen noodles but use only part of the seasoning packet - I pre cut stuff like green onion, shredded carrots, mushrooms, asparagus, zucchini- you name it - you can even use pieces of hot dogs, chicken, etc. Store the additions in bags in the cooler or fridge and let the kids pick what they want to add. Super easy to cook and each kid gets to add what they prefer.I’ll make chili ahead of time and freeze in freezer bags. Heat some water in a pot and drop the bag in. Grill some dogs and you have easy chili dogs.
