you can look at my journal and see what i eat and modify if to your gender, height, weight, goals. but i eat a lot of the staple body builder vegan foods, all approved by my coach who is a pro and got me to my first competition..you are probably gonna want to eat a lot higher carbs than me if youre just getting started i assume you want to gain mass....i would say eat clean, frequently, and a variety of things...i prep my food for the next 5-7 days but then when im not dieting and counting every single macro i try to switch out veggies and legumes for different kinds as best i can, but not too easy when im trying not to go crazy on carbs cause im on a modified diet for another competition. none of the foods i eat are that expensive...for you i would recommend dried beans. not sure where u live but i can get a bag for between 1 and 2 dollars and one bag of chick peas makes about 7-8 cups cooked...lentils, rice, bananas, broccoli, tofu, nuts...peanut butter. its really amazing how healthy you can eat on a budget and how much bang you can get for your buck - but cutting gets expensive cause you need to really hunt down low carb stuff like protein powder and various supplements but for a beginner its not as complicated and expensive as one might think. message me if you want more input.
