How do I cook food that is at the intersection of cheap, fast to prepare, good tasting, and good for me? It is fairly easy to satisfy 3 of the 4 conditions with any given meal. All 4 are hard.
So far I only really have various soups/curries, and omelettes. I'm on the lookout for more, though it is tedious looking through "normal" recipes and trying to figure out which ones can be made to satisfy the conditions by cutting corners and still come out okay.
edit: I guess I should note that I have a definition of "healthy" some will consider weird. I don't consider bread to be healthy food, it is nutritionally empty space. Most of the nutrients you see listed on the package come from enrichment which does next to nothing for you bioavailability wise. The carbs I require for physical activity come from potatoes.
This might not be exactly what you're asking for, but it's worth noting the power of leftovers if you haven't already! If you're bothering to cook, most of the time it hardly takes any more time to cook twice as much as you're going to eat right now, or even more. That's at least one more meal for the next few days solved. If you have a freezer, developing a small stockpile of frozen leftovers in it is excellent for the fast-to-prepare dimension. Also note that preparation time speeds up a lot with practice.
With Alicorn's permission, I'm resurrecting this thread.
I'll start off with one of my own: What kinds of exercise can I do at home (I do have 5- and 20-pound weights), and what are good ways to get motivation to do so regularly?
