Dorm fridge chili and a weird grocery win

My dorm fridge currently contains four identical containers of lentil chili because I keep cooking like my appetite is still the old one. I’m about three months into a GLP-1, and I’m a broke student, so my cheap-protein rotation is eggs, cottage cheese, canned tuna, and whatever lentils are on sale. Before this, I’d graze through the dining hall like a human vacuum and then buy vending machine snacks at 11 p.m. Now I can eat a real bowl, feel done, and put the rest away. It’s not dramatic. But my food spend dropped about $30 last month, and I actually finish the yogurt before it grows fur. The funny part is I still make enough for three people out of habit. Anyone else meal-prepping for the appetite they used to have? What’s your cheapest no-fuss protein that doesn’t taste like punishment?
