I get 100-120g of protein per day pretty easily, from- tinned tuna, cottage cheese, eggs, smoked salmon & chicken breast, maybe some legumes, fish in soup, etc. I also use Lidl High protein products, which I rate.
Typical day (yesterday) 120g cottage cheese, 50
g smoked salmon, 100g chicken breast, fish soup, bean casserole, Lidle high protein pudding. (That’s the protein food only) Total calorie intake 1200. Comfortable, satiated but not stuffed.
