Also, stir-fry is almost by definition keto friendly. Meat and vegetables. Easy "refrigerator velcro", put whatever you got that's about to go bad in a skillet with some sliced-up protein and put the heat to it for a bit. Might need to put the onions and garlic in before the meat and the veggies but the order of operations will depend on what veggies you're cooking with. Did some stir-fry pumpkin-chunk tacos a few years back, I think with some pork, and it turned out a lot better than I had any reason to expect. I wish I could remember what I had put in the skillet. Obviously don't serve it over rice.
Along the same lines, you can do keto curries. India-inspired cooking is an enormous rabbit hole to explore. As Hinduism holds vegetarianism as a central tenant, there is a huge variety in Indian vegetarian food that you can add meat to, if you're trying to eat more vegetables and less meat and grains. Unlike Western vegetarian food, they don't try to trick you into thinking this plant matter is actually meat; they'll let vegetables be vegetables. I made a cauliflower curry that was excellent and not at all what you think of when you think of cauliflower; IIRC it was cauliflower, spices, coconut milk, onions, and garlic. There is a learning curve here with regards to the spice palette but the payoff is worth the work. They do eat a lot of breads, lentils, and potatoes, which isn't low-carb, so you'll have to read recipes pretty carefully.
