For eggs, I like frittatas a lot. Just take a bunch of veggies, and saute in a medium-size nonstick pan (about 9-10"). (Onions, zucchini, peppers, asparagus, broccoli, spinach, whatever. For carbs, you can add diced potato or sweet potato, or cooked rice/grains of any kind. I've even made ones in which I pour just enough boiling water over a scoop of cornmeal to cover, let it soften and cool, then beat the eggs in and pour over the veggies.) Season to theme (e.g. onions and peppers with cumin, garlic and chile powder for a kinda Mexican air; spinach and garlic with Italian seasonings, etc.). Pour the eggs on top, cover, turn the heat down to medium-low, and cook for 10-15 minutes (depending on the number of eggs) until the top is just set.
Now you have two options. If your pan is oven-safe, or you want to risk the foil-over-the-handle trick, you can preheat your oven broiler, and stick the thing under it for a few minutes to toast the top. Or else, flip the entire thing (carefully) using a plate, reverse it back into the pan, and cook till lightly browned.
These are very nicely portable (just cut 'em in quarters and plonk into a container) and are good at room temperature, or even cold. Plus they are infinitely variable, according to your tastes and fridge.
Then there's stir-fries, which are dead easy if you keep a batch of cooked brown rice and some soy sauce or Bragg's in your fridge. Again, you can use whatever veg you have (even a frozen "Asian blend" will do in a pinch) and any protein, or mix of protein, you like. Even eggs, if you want.
try adding olive oil & some balsamic vinegar. i've had tuna & mustard, tuna & salsa.
Sucks, because of the cost and because I don't think I can go back to doing the bulk cans of tuna at Costco. lol
