Just throw the butter out and use lard
I'm in the office all day. I get a 'packed lunch' - a small bag of mixed nuts and maybe a small tin of tuna or some dried meat, which I eat sometime between 10am and 3pm.
I might have snacks when I get home, but mostly it's just dinner.
Some pretty average dinners are
• BBQ pork belly (nothing else)
• T-bone steaks (nothing else)
• Seafood - ie. prawns, garlic, fish (fried in lard with almond meal), octopus, spring onion, squid, pepper.
• Roast pork, broccoli, cauliflower, carrot, pumpkin (= dinner with the parents)
• Salmon and 100% beef sausages.
