i need 140g+ protein.

the entire last week, i've been consuming peanut butter sandwich x2, boiled eggs x10, and 2-litre milk. i did gain weight, but i also experienced nasty breakouts, flatulence and bloatedness-- probably because of the milk. (lactose intolerance)

i wanna cut milk out of my diet, but i can't think of any alternative how to get that 60g+ worth of protein that i can get from milk.

i wanna save money so i don't wanna buy any protein supplements. i also rather prepare my food but i only have rice cooker and my fridge is faulty (it only cools, but can't freeze).
