Fresh Veggies and fruits can get expensive and they do not keep you full. Pasta is a cheap way to get full on a budget. Spaghetti, alfredo, tuna casserole. All cheap and easy things to make.
I eat a banana(cut in half) with two tablespoons of peanut butter on top and sprinkle granola and raisins on top. That keeps me full like all day haha. However, raw fruits and veggies will help a lot. Also, oatmeal. Make sure you are drinking plenty of water as well
Ohh and my fave snack is FRIED ZUCCHINI! idk if u like it but zucchini ia cheap and i just need an egg and flour with a bit of salt pepper. Fry and dip in ranch :) maybe $4 and just keep ur zicchini fresh in the fridge.
Apples and veggies yes. Get a jar of peanut butter for dipping. Dip apples, celery,carrots...yummy lol and cheap. Make casseroles and freeze them so u can reheat. Chocolate milk is filling and good calcium+ vit D. Get a cheap powdered mix and store brand milk. Quesadillas arent bad in price. Cheap tortillas, store brand block cheese,and salsa. Pancakes are cheap. You should try shopping at a 99 cent store they have great choices for a buck. Hope that helped a little. Take care.
I snack on raw almonds great for you and they keep me feeling full.
Fresh fruits and veggies, make sure you buy in season. If you have a local farmers market, they're usually cheaper than a grocery store, or if you can find a farm where you can pick your own fruits, those are super cheap.
