You'd be surprised how far you can get making dishes you already like and just leaving out the meat. If it won't work without a protein, just swap the meat out for button or king oyster mushrooms, seasoned appropriately.
Meat free mince and nugget type things are getting pretty good these days. Not as good as the real thing but close enough to it. There is a big variation in quality between brands though, so you need to find ones that are available, affordable and dont taste like cardboard. Impossible burger is quite good for most purposes.
Alternatively, just fucking google vegetarian recipes, this is the worst place on the internet to get good advice about vegetarian food
