I start the day with 50g walnuts, 50g oats and 50g protein shake. For lunch I will generally have two cans of tuna, some microwavable vegetables ( broccoli, carrots cauliflower) and then sprinkle pepper on top..Thats quite affordable. Sometimes I'll have sliced lean beef with horseradish instead of the tuna for flavour. You can make microwavable scrambled egg ( cheap as hell) or even grab some pastrami also. Salmon is another one but it depends on how much you want to spend, eggs are so cheap and you could have some wholemeal bread + scrambled egg for about a week and it would be cheap as hell and easy to prepare.

I sometimes get an entire cooked chicken from the hot section of the supermarket and just cut off the lean bits and gobble it down like a monster. I found one for 10p UK which is liek 20 cents discounted the other day, I took a pic of it because we were laughing at how cheap it was. Delicious too.

I find pre-workout the best thing for me is oats + 500 ml water and protein.

Make chicken on bulk i like to grill my chicken, add some seasoning, brown rice, and broccoli, u can also get Turkey burgers eat them with what bread, lettuce tomato light mayo n even mustard, i love those. Go to YouTube and tire bodybuildibg recepies, get good food from there.
