Eggs are good for baking (muffins & cookies for me) and I like them scrambled with salt & pepper. Plain eggs can be spiced up with cheese, vegetables, and (if I'm feeling fancy) a tiny bit of fruit. Eggs pair well with potatoes for certain dishes; I sometimes make egg sandwiches on toast (often adding cheese and/or fish); boiled eggs are nice when I'm feeling lazy, and I occasionally pour a raw egg into freshly-cooked rice (the heat from the rice cooks the egg as it's mixed in, so it works as a sort of glue to hold the rice together; the rice can then be shaped while still hot). Eggs and cheese also make a good filling for a hollowed-out red bell pepper.
I usually eat chicken with rice or in a burrito, and if I want meat on a pizza I'll sometimes get one with chicken (since I try to avoid red meat). Chicken works well with noodles or potatoes, too, and chicken salad is always nice, on its own or on a sandwich.
