Diversifiny protein sources for a resistance training individual

1. I really like salads, especially the chicken salad I make and I could eat two a day but that’s 400 grams of chicken, any alternatives that require as little prep as chicken breast? I was considering tuna but I can’t eat it daily so I might need something else I was thinking cottage cheese, quark and tuna in between Each around 200 g a day
2. For reference I am currently in a caloric deficit, resistance traning 5 days a week, I am 186 cm tall and weight 90 kilograms and I am the ripe age of 22. I would consider myself fairly muscular. My family has a long history of cardiovasular problems and chornically high cholesterol.
