Baked chicken - There are a ton of these recipes but they all come down to basically the same thing: Brine, put seasoning on, cook it in the oven, let it rest a few minutes, done. It takes a little time from start to finish, but the total investment of actual effort is like 5 minutes. (I keep a little tupperware of premixed seasoning.) Combine with a tray of vegetables in the same oven and/or some rice or something. (I actually do this with skin-on chicken thighs instead, but it's basically the same)

Steak - Learn to cook a good steak, it's fuckin magic. Again you can find recipes online. Let it warm to room temperature first, put salt and pepper on it, sear the outside 30s or so on high heat including picking it up and hitting the edges, then lower the heat and flip it every 60-90 seconds to let it cook, and at the end dump some garlic and butter in the pan to flavor it. Let it sit a minute or two and you're good bb.

Blueberry pancakes - Use fresh blueberries.
