What I use for ready to grab foods or things to eat if I don't have time to cook are: chicken salad and egg salad I make ahead of time, hard-boiled eggs, like you mentioned, cook an eye round and slice and put in the refrigerator to eat with mayo, frozen veggies I can steam real fast and throw butter and cheese on, get salmon at Costco, cut into individual portions and freeze...they take only 2-3 minutes to microwave (always cover, though...to prevent messing up the microwave), always keep on hand: shredded cheese, feta/goat cheese, eggs, veggies, fish portions, pre-cut salad mixes, chopped bacon, farmer cheese....and of course, butter and mayo.
Other than those, when I have the time, I will cook all sorts of chicken, turkey, etc., omelets, roasted/sauteed veggies, etc...when I have the time to cook or am not so hungry that I can't wait for something to cook.
Though I usually can wait, since I have such great appetite control on Atkins. But having stuff handy is great for times when, for instance, there are visitors here (usually family) who are eating stuff like pizza, etc...and don't want to go cooking in front of them so can grab Atkin's friendly stuff out of the fridge....or days like the recent ones I had where I'm in Annapolis all day, didn't eat, and come home late, hungry and too tired to cook.
