Reddit reviews The High-Protein Vegetarian Cookbook: Hearty Dishes that Even Carnivores Will Love

I think the best thing to do is to grab a cup of coffee to go and head to your local public library. Vegetarian cookbooks are usually around 641.563 if you're using the Dewey decimal system. Grab a bunch of cookbooks, take them to a table, and start looking through them. When I was starting out I preferred cookbooks that had a lot of photos, as I wasn't always sure what things were supposed to look like. Now that I'm a fairly confident cook I can usually read an ingredient list and set of instructions to know if a dish is something that would appeal to me. Stick a bunch of post-its on the recipes that interest you and sign out a handful of the best books!

There are cookbooks that focus particularly on high-protein vegetarian and vegan meals, but in general you just want to look for recipes with all of the high-protein ingredients you know and love.
