Hi there, Blue! Thank you so much for the ideas! How brilliant to use the frozen chili as an ice block.
And, I LOVE flax muffins.
Here's what I ended up bringing:
Steak for Friday night and dogs/brats for Saturday night
7 layer salad to use as a dinner side
Keto pancake batter for Saturday morning
Low carb Mission tortilla wraps (it has been a LONG time since I bought these, and realize they're not for everyone) for wraps (made the night before) and breakfast burritos.
I precooked sausage links, shredded cheddar, and cracked eggs into a plastic container for the burritos the night before we left.
Dark chocolate dipped strawberries for dessert both nights
Boiled and deviled eggs, celery and cherry tomatoes for my mom's dip (sour cream, cream cheese, mayo, spices, bacon), pecans, and Whisps "crackers".
Saturday afternoon I made a snack plate in lieu of lunch: 3 types of cheese, summer sausage, a few dill pickles, black olives, nuts, some of the Whisps and a bit of dried fruit for DH.
We did NOT go hungry.
