    Spinach, Caramelized Onion & Roasted Pepper Open-Faced Sandwiches from Vegetable Literacy
    I can never, ever pass up the opportunity to make a recipe that involves caramelized onions. Are they a pain to make? Kind of. Do they take for-freaking-ever to cook down? Absolutely. But they are always worth it. When I was given a list of recipes from Deborah Madison's Vegetable Literacy to choose from for this post, my eyes immediately went to the open-faced sandwiches topped with caramelized onions. There was no way these wouldn't be delicious!

    Vegetable Literacy by Deborah MadisonCaramelized Sweet Onions
    The sweet onions and thick slices of roasted red pepper paired perfectly with the salty cheese and earthy spinach. And aside from the time it took to caramelize the onions, these sandwiches were easy to make too. This is why I love Deborah Madison's cookbooks—they elevate vegetarian cooking beyond veggie lasagnas and burgers, but in a way that's not intimidating to the average cook.

    Caramelized Onions on BreadVegetable Literacy

    Vegetable Literacy: Cooking and Gardening with Twelve Families from the Edible Plant Kingdom, with over 300 Deliciously Simple Recipes was released this week and I was lucky enough to get a copy to review. As a vegetarian (and a fan of Deborah Madison's work in general), I appreciate this book for its inspired recipe ideas, but as a gardener, I loved this book for the background it provided about different vegetables. Vegetable Literacy isn't just a cookbook, you see, it's a reference book too, dividing vegetables into different families (The Sunflower Family, The Cabbage Family, The Grass Family, etc.). Each vegetable receives its own write-up, with information about its origin, different varieties, and tips for cooking. If you have Vegetarian Cooking for Everyone, this format with information about each vegetable followed by tips and recipes will be familiar to you. And if you love Vegetarian Cooking for Everyone, you will love Vegetable Literacy too. Like Deborah Madison's other books, I know this one is going to be well-used in my kitchen.

      I adore this book! This weekend is an all-Vegetable-Literacy-all-the-time cooking extravaganza. The tartine looks beautiful - I can't wait to try it! Like Brian said above, veggie sandwiches are so often a fail. This one definitely is not. 🙂

      These are beautiful! I love caramelized onions, but the time factor means I've only made them once or twice. I feel like I could eat a whole tray of these, though.

      I seriously think if my fiancee had to pick three foods to eat for the rest of his life, he'd pick spinach, caramelized onions & pepper. Seriously. Obviously I'm totally making this for him!

      Do you have a George Foreman Grill? When I worked at a restaurant, we would caramelize onions on it! It totally cut down the time! Just slice, toss with some olive oil, salt, pepper, layer them on the grill, and close the lid! Super easy! Enjoy!

      Your recipes are superb. My husband's vegatarian and he spent 2 years eating the same dish everyday. *poor guy*

      After trying your recipes, he always comes home eager to see what's on the menu and its just amazing to see that smile on his face.

      thanks for sharing these lovely recipes!

      I'm not really a fan of fresh pepper (any unprocessed capsicum family) - but the rest of it looks amazing. Would it still taste good without the pepper or do you have any recommendations for a replacement?
