It sounds silly, but when I’m on business trips I almost really like the Darden style restaurants for this reason. Think like Olive Garden, Chili’s etc. Sure it isn’t great food but damn is it a lot for a little. I’ve gotten a big ass bag of chips dipping sauce on top of burgers fries dessert for about the same as a small meal from Taco bell and a quesadilla from there. It’s almost double the amount of food for the same price, and they’re almost easier to deal with because they now all have online ordering. Place the order online as I’m about to leave work, go stop on the way and go pick it up, done deal and I got something for the next day too. I almost prefer takeout style restaurants like this now over “fast” food that’s anything but in their drive thru line.
There’s little hacks for certain foods too if you can’t cook worth much or don’t want to bother to. For example I don’t want to bother with cooking a chicken, so I’ll go get one hot off the rotisserie chicken counter at Walmart or HEB. $6 for a whole ass chicken already hot cooked and ready to go, take it home and shred it. If it’s hot the skin and legs taste good as a snack of itself while you’re processing it and you can hand shred the breast / thighs / etc and save it for using in meals. It’s how I make quesadillas or chicken alfredo really quickly.
