Healthy recipes for college student on budget!!!

Kelsey
I'm probably going to be living in dorms for my next semester which means I'll be on my own pretty much. I want to try and eat healthier while I'm there, but of course I won't have a ton of grocery money. Do you know good healthy and cheap recipes (mainly for dinner meals) I could make? I estimate I'll have between $50-no more than $70 for groceries per week. 
​I'm thinking for breakfast I'll probably do yogurt with fruit and granola a lot, fruits and nuts for snacks, and sandwiches for lunch. 
​I don't have any dinner ideas though!
