Travel 3 weeks post-op

I am 3 weeks post-op as of today, and am leaving for a 4 day trip tomorrow. According to my plan, I’m on soft foods. I started some VERY soft foods last week (again, following my plan), and have handled the few things I’ve tried well. Still mostly relying on protein shakes (which I don’t like room temp). I’m just looking for ideas of what to eat while we’re out and about since I won’t exactly have a fridge or microwave handy the majority of the day. I’m blanking on what types of things I can carry on me/in the car.
