Preheat your oven to 425F and line a baking sheet with parchment paper.
To make the pickled veg, in a medium bowl, add your cauliflower, carrot, vinegar, water, salt, and sweetener. Let sit for at least 30 minutes or overnight to pickle.
Add oats to a high speed blender and blend on high into a flour. Add chickpeas, onion, herbs, garlic, chia seeds, 1 tablespoon olive oil, cumin, salt, pepper, and cinnamon. Blend until thoroughly mixed/smooth, using your damper tool to encourage blending. Scrape the side and under the blade as needed.
Drizzle remaining 2 tablespoons olive oil onto the baking sheet and spread it around with your fingers or a pastry brush. Use a small cookie scoop or heaping tablespoon to form your falafels into balls and place on the baking sheet. Flatten slightly with your palm into ½-inch thick rounds. Brush some of the oil on top so it’s coating on both sides. Repeat until falafel mixture is used up.
Bake for 15 minutes, or until browned on the bottom, then flip and bake for 6-8 more minutes, or until lightly browned on the other side.
In a small bowl, whisk together the tahini, water, lemon, salt, and pepper until smooth. Thin out with water if too thick. Taste and add more salt or lemon, if needed
Add romaine, tomatoes, avocado (if using), rice or pita, falafel, and pickled veggies to your bowl. Squeeze lemon all over, drizzle the tahini sauce over top (save some to have on the side, trust me you’ll want more!), and sprinkle with feta (if using), and black pepper.
