I skimp on so many things. Cheap booze if I wanna get drunk, cheap underpants cos who cares, frugal with petrol etc where possible. However, meat is one thing you can enjoy; always get mine from local butcher - tastes amazing, good value (better than supermarkets) and all food is top quality (grass fed beef isn't a thing here, all Irish beef is...). Just a thought, maybe save the penny pinching for other areas.
By the way, a lot of supermarket chicken (breast meat etc) has water added by putting it in things that look like giant washing machines adding water holding agents (salt, beef, pork) and water. When you fry diced chicken there should be next to no water, fry shitty supermarket chicken you have to strain it.
