Tools.
If you don't have them, buy them as you need them. Seriously. Here's a checklist for ya:
1x 4 quart pot (stockpot, saucepan, whatever). Nonstick optional, not recommended. Useful for big batches. Not really necessary if you're keeping your cooking smaller scale, but it'll be handy for things like chili and large-batch soups -- simmering dishes.
2x 2 quart saucepans. Yep, get two of them. If you can find stainless steel, that's the best. Avoid nonstick on these -- things usually need to be scrubbed from them, and scrubbing nonstick with an abrasive pad just destroys it, it's better not to have at all.
1x 1-quart saucepan, also stainless. Because sometimes you just don't need to heat up 2 quarts worth. 1 quart is perfect for stuff like rice and mashed potatos.
1xSkillet, with a lid. Definitely non-stick, preferably with a glass lid so you can see what's going on in there. 12 inch is the right size for just about everything.
1xBaking Pan, 9x9 or 9x13, preferably glass. Especially if you're just starting out cooking, glass is the best, because you can see where stuff is burned onto it easily, and you can scrub at it or scrape at it with metal things without hurting it.
1xSpatula, preferably as thin as possible, definitely coated. You want to be able to use it in a nonstick skillet, and metal spatulas will just destroy them.
1xWire whisk. Cheap, good at beating things (better than a fork).
1x2-cup glass measuring cup. Usually, bachelor cooking is imprecise, but you still want to measure things like water, and milk.
1xServing spoon, nonstick-friendly (ie: plastic, or plastic-coated).
1xTongs. Best for spaghetti, great for flipping things. Coated or not, doesn't matter much, they shouldn't spend too much time near your skillet (that's what the spatula's for).
2x hotpads. Better, make one of them a mitt type, so you can grab things with one hand and serve with another.
1x Cutting Board (small is fine).
1x Big kitchen knife (like, 8-9 inch blade or so)
