>>21468224 (OP)50g ain't even that much.
3 eggs in the morning is 18g and small af (not hardboiled, it retains too much volume); 1 cup of milk is 8g, 2/3 cup greek yogurt is at least 15g, or 1/2 cup of cottage cheese is at least 10g. Peanuts, peanut butter, cashews, or almonds are at least 5g per 1/2 cup; 1/4 raw beans like lentils, pintos, or blacks are like 8g, and chickpeas are like 10g; and other animal proteins are like 20g per serving (varies raw/cooked measurements, bone sometimes included).
I had these on an old food list I made.
If you can't think of anything else you weren't trying much. 50g is so easy that you don't even need protein powder.
