Madhur Jaffrey's books are always good. How about her 'World Vegetarian' book?
I'm vegetarian. Food never need be boring or bland. Much of Indian cuisine is vegetarian and that food is super spicy (not hot-spicy but tasty spicy).
Two great resources:
Easy recipes include:
Vegetarian eating gets a bad rap because people think they need to replace their usual hunk of meat with tofu or another meat substitute. If you look at cultures that eat vegetarian (India, Buddhist China), you see they eat stews and saucy stir-frys.
Good luck and have fun experimenting!
World Vegetarian by Madhur Jaffery has so much information in it, it is wonderful! I am no longer a vegetarian but still love that cookbook.

Note: I'm a happy omnivore, but have a lot of friends that range from mild veggie to strict vegan.
I'd say there are several good reasons to take it on, even if you don't share the same perspective on the morals of eating meat. One of the biggest is that young veggie folks left cluelessly making food for themselves tend towards the morning star brand style garbage food. You don't want that.
You also can approach it as a purely intellectual challenge. How can I convert some of my favorite dishes into a meatless version that hits the same concept, even if it's substantially different. You'll stand to learn a lot about how to use stuff you already know in new ways. You also can start thinking about how to take a whole meal menu and split it into separate everyone, meat eaters, special vegetarian treat options for everyone.
That last one can be a big deal, especially for young folks. While I may not share the particular belief, I've seen young people whose families just reject their view out of hand alienated pretty hard by always being relegated to just eating the side items they find least objectionable. Making something *just* for the veggie folks as a unique treat, even as an omnivore, makes me happy.
Madhur Jaffrey's encyclopedia of veggie recipes (https://www.amazon.com/Madhur-Jaffreys-World-Vegetarian-Meatless/dp/0609809237) is a great resource if you just wanna get one book with a ton of options. I'm pretty sure your whole family will find some new favorites in there.
This book has a bazillion recipes. The ones I've tried have all been decent.
