I'm not a vegetarian, but I usually go meatless a few nights a week mostly just out of preference.
Have you tried Pinterest? I get a lot of my recipes from there. I usually sit down with a cup of tea on Sunday mornings, scroll through my recipe boards and make a menu and shopping list.
This homemade pad thai, while inauthentic, is awesome. Restaurant pad thai is always orange and goopey (ew) so I avoid it. This is so easy - I add shrimp, but the recipe as written is vegetarian.

This olive cous-cous salad is awesome. You could even try it with quinoa for more protein:

If you wanted to do breakfast for dinner you should try migas! This is the recipe I use, but you could literally add anything you want to it:

This one is a "Mexican" pasta recipe. The recipe calls for chicken, but you could easily omit it. It's not healthy by any means, but I loved it and it had a pleasant spiciness!
