My 18 yr old daughter is vegetarian, so I have had to get creative on meat substitutes.
A favorite that we ALL eat is vegetarian tacos. I dice potatoes and fry them a bit, then add a jar of salsa and let it simmer for a while. Make some spanish rice but substitue quinoa for the rice as it has more protein and heat up some pinto beans. We stuff tortillas with the potatoes, rice, guacamole, cheese, lettuce, tomato, a bit of sour cream and beans on the side...SO YUMMY!! You don't even miss the meat.
I also substitue potatoes for chicken in teriyaki and again use the quinoa in place of rice.
We eat a lot of pasta with a ton of vegetables in stead of meat balls.
Also vegetable stir fry is really good and we don't miss the meat there either.
Good luck!!
