Interesting meals while cooking for 2 with limited kitchen gadgets

[Soliloquy]

For the next 4-6 weeks I'm at my mom's house (she's in assisted living) with just one of my teens. She has a regular kitchen but no instant pot, food processoor, slow cooker, etc. Also, I am so un-accustomed to cooking for only 2 people! I'm used to cooking for 7 and making enough for two meals so I don't have to start from scratch every night.

I've done spaghetti, burritos, and baked chicken with vegetables. And I'm totally out of ideas. I could just eat vegetables and some protein and be fine, no complaints. But if I keep cooking the same old thing all the time my teen starts asking for carryout and I'm trying to save money. (I'm not trying to go overboard catering to him but I'm also asking some things from him right now that are hard and not necessarily fair, so I want to give a little on the food.)

I can look for a slow cooker at Goodwill. But I doubt I'll find any other other appliances I'm used to for cheap.

What do I cook for 2 that's interesting?

I'm thinking I'll make stir-fry tomorrow. We both love that. Oh, and my mom's kitchen only has very basic spices and I don't want to spend a fortune starting over on spices, either. At home I have a stock of spices for making all our favorites. But I can buy a few. There are Penzey's everywhere, here.

I also plant to go to Costco soon, but I have to be careful and remember there's only 2 people to eat whatever I buy! It's a huge adjustment in my thinking.

I have easy access to Aldi, Trader Joe's, Costco, Whole Foods, as well as regular supermarkets.
