The approach I took in college was to ease in to it, not by slowly dialing down the amount of times I ate out, but by buying boxed meals and adding to them: Buy a cheap food that you can stand that is boxed (mac and cheese, canned soup, ramen) and add some vegetables or pre-cooked meat you like to fill it out. Cook the vegetables with the meal and follow the directions on the box. Even after eight years, I still do this several times a week to have easy cooking days. Next, try cooking something a little more involved but use a prepared base. Buy pasta or a pizza crust and add your own toppings plus store-bought tomato sauce, for example. Again, the directions should be on the packaging. Next, choose some foods that you like but don't know how to make yourself. Find a simple recipe and pair it down to the bare minimum. For example, I like lasagna so I found a simple recipe that only had a half-dozen ingredients and bought noodles that don't need to be pre-cooked. Mix it up with a fully prepared meal (either order take-out or a frozen pizza or something) once or twice a week. When you get started cooking, it can be easy to miss a key nutrient that you need and having a cheat-day where you eat something you're more used to and can't mess up makes things much easier. When you're starting up, stick to 1-2 cuisine types. Each cuisine has its own staples and commonly used spices, that they combine in different ways. Figure out what makes good staples for your chosen cuisine and how to prepare them (not necessarily from scratch). Find the commonly-used spices and add them to everything, experimenting to see how much you want to add. For example, Italian food uses a lot of pasta or pizza crusts. Fresh pasta tastes much better than boxed pasta, but isn't shelf-stable. Pasta cooking times are short but generally somewhat precise. To cook Italian pasta, you'd want to learn how to tell that pasta is fully cooked. Mexican food uses rice and tortillas instead of pasta and pizza crusts. Pre-cooking your tortillas makes a huge difference. Cooking rice in a rice-cooker is easy, and it's do-able in a pot. The trick to cooking rice in a pot is that, since it's steam-cooked, checking the rice early can really slow down and mess-up the process. The first several times will be slow and messy, but once you figure out how long to wait it's actually quite low effort.
