Black bean tacos. Drain and heat a can of black beans, mixing in taco spice. Heat up taco shells. Serve on table for people to make their own with salsa, guacamole, grated cheese, jalapenos etc.
American alfredo sauce is a great alternative to normal cheese sauce. Melt butter in pan, add chopped garlic and fry for a minute, add grated parmesan and whisk quickly. You can do it with pasta, but it's also nice on chicken.
Naan bread pizzas.
Buy pre-made falafel or koftas and serve with pitas or wraps, houmous, cucumber, salad etc to put in them.
Thai red/green curry is always quick.
I would highly recommend an instant pot/similar programmable pressure cooker though to cut time. I use mine all the time for veg chilli, quick soups, and back when we used to eat meat it was amazing as you can cook from frozen.
