Learn pasta, you can basically throw anything in with pasta and make it good. My goto after work dinner is just frying up onions and garlic, get that fragrant, add some cherry tomatos, and simmer with white wine until it all breaks down. Add some starchy pasta water and then whatever greens you got around, toss the pasta in and serve.
Here I wrote down my process for this. If you cant tell I dont really use a recipe, I just wing it every time because the end result is usually ok.
Oil to pan, I do olive, dont let it get smokey
Onion, however much you want, let it get fragrant
Add Garlic until fragrant
Red chili flakes, or fresh cayennes if you have them
Add cherry tomatos
Let the tomatos come up to temperature
White wine, use your best judgement, around a cup to two cups. Sub with normal water if you dont want to use wine
Clam juice if you have it, just a splash
Simmer and start boiling your pasta, make sure the water is salted
Half way through the pastas cook, ladel one cup of pasta water to your pan
At this point if you have green veggies add them in, broccoli, spinach, peas, basically anything you want to just use up
When pasta is a minute away from cooking, transfer noodles to pan
Toss and combine pasta with sauce and veggies, it should thicken up nicely
Serve with black pepper and whatever cheese you like
This dish comes together in 30 minutes, and allows me to use whatever I got laying around to add to it. Beans? Shrimp? Cabbage? basically whatever can just be added.
You mentioned stocks, you can make your own and sub the wine or water here for more savory tastes. I like to make whole chicken stock which is really easy to do, and is also a great way to use an entire bird for soups.
Learn this recipe by heart, its good and will not disappoint. You can use older veggies in the stock as well. Heres a pic of some I made a while ago with my homemade bread.
