World Vegetarian Day Veggie Casserole

Ode to World Vegetarian Day! This is the easiest Roasted Tomato Vegetable Casserole you will ever make. Perfect for the occasion!


So as World Vegetarian Day rolls around (October 1) I wanted to share a recipe that is not only one of my favorites, but it is also on heavy rotation at the Beets house. Vegetable casserole is probably one of the easiest and more popular dishes prepared on Meatless Monday. I love this Roasted Tomato Vegetable Casserole.


The best part of a veggie casserole is the versatility – you can chop up any veggies you have lying around your kitchen. In this version I used sweet potatoes, white potatoes, an orange bell pepper, zucchini, squash, carrots and ripe tomatoes. I made it completely Vegan by using a product called Parma Zaan (<—Amazon affiliate link) in place of parmesan cheese. Its ingredients are almond meal, sea salt, nutritional yeast, dehydrated onion, citric acid – none of that funny stuff. And it tastes great on just about everything from spaghetti to popcorn. While it is sold on Amazon, I have also found it Whole Foods and specialty Vegan markets.

I think this particular casserole is very Fall-friendly with the use of sweet potatoes and squash -and no- there is no pumpkin here, but I guess you could add pumpkin if you want. Brussels sprouts, broccoli and/or cauliflower would be great additions.
