Why are you assuming all the cooking duty? What is the situation? That could really contribute to my answer.
Without knowing the reason, my initial response is, why can't you prepare everything else and leave handling the meat to one of the other adults present? They're talking burgers and grilled chicken, not complicated curry dishes or stews with the meat integral to the meal. You could readily prepare salads and roasted veggies and grains and desserts and so forth; why can't one of the other adults present manage slinging the burgers on the grill?
What is your opinion on your mother's thing about your kids eating the burgers? Do they eat meat, or did they go veg with you? I would be livid if my mother tried to tell me what my kids should be eating. If you're not cool with them eating that meat, it's *your* say, not hers. She shouldn't be pressuring you or manipulating them to eat it. If you prefer to avoid any drama by just going along with her on that point, or if they're omni and will give you a hard time if others are eating meat without them, you could maybe pack along enough of the better quality meat you described, frozen.
