I find it quite easy, but my requirements are vastly different than yours. I don't eat meat, so that takes out a huge array of easy meals (burgers, kielbasa, beef stew, etc. [for tips on this stuff, I suggest on-line recipe sites. search for a dish you know you like {"beef stew" or "chili"} and pick the highest rated one. the comments are almost always useful in improving the dish])
Things that I can prepare and then forget about free me up for other tasks. Stews, chili and baked goods are great options here.
Things that take <30min (cooking pasta, chopping vegetables, stir-frying meat in your case) are also awesome when you're strapped for time. My TexMex dishes are also generally quick and take this form: fill tortilla with stuff, include some sort of sauce from a can or home-made, bake; fry; or broil tortilla, eat.
For lunch, I just cut up this week's random assortment of vegetables (cucumbers, tomatoes, peppers, sprouts, etc.), layer some hummus on some sort of bread (pita, sliced, bagel, tortilla, etc.), and place vegetable mix on bread.
Breakfast is oatmeal, preferably with blueberries.
I'd say my daily home made meals are pretty average tasting, but, having never really frequented fast food, my stereotype of delicious food is a 20$ or more plate in the North End. Imagining that cost makes my pasta with sauce and cheese acceptable.
