Sounds like you’re trying to start a keto diet (no carbs and heavy protein). Check the keto subreddit for tons of info on keto and keto food ideas.
Also just a tip but maybe don’t reply “nasty 🤢” to people who are just nicely answering your question, lol.
Eggs, meat, veggies, seafood.
Every weekend I usually boil about 20 eggs and fry up about 20 shrimp. During the week if I want a quick lunch I quickly chop some veggies, add some greens, eggs/shrimp, sometimes cheese, dressing, salt n pepper.
