Meal prep for a finance student with little money

Hello. I am a 20 year old who is going to university and I am studying finance. I am also on a budget, as I am living alone but I am paying for my university studies by myself. I don’t have much money to spend so I am looking for some cheap meal prep ideas. I am not much of a cook but I am eager to learn. So far I have been trying to meal prep chicken, rice, sweet potatoes, and broccoli. I am also trying to drink a lot of water throughout the day to help with weight loss. I usually give myself $60 per week for groceries, so I am looking for any meal prep ideas that I can use on such a limited budget. Any help would be appreciated to help me meal prep a lot of food for cheap.<br><br>TIA
