Falafel Mushroom Loaf

Preheat oven to 350 °F. Lightly coat a 8 1/2" x 4 1/2" x 2 1/2" loaf pan with cooking spray. Working in batches, pulse mushrooms, onion, garlic, coriander, cumin, and cardamom in a food processor, scraping down sides as needed, until coarsely chopped, 30-45 seconds; transfer to a large bowl. Heat oil in a large skillet over medium-high. Add half of the mushroom mixture and cook, stirring occasionally, until the edges begin to crisp, about 5 minutes. Transfer to another large bowl; repeat with remaining mushroom mixture. Meanwhile, pulse chickpeas in food processor until coarsely chopped; add to bowl with cooked mushroom mixture. Add egg, chickpea flour, cilantro, parsley, and salt and gently stir to combine, being careful not to mash mixture too much. Spoon mixture into prepared loaf pan and bake until edges are browned and center is completely set, 75 –90 minutes. Transfer pan to a wire rack and let cool 30 minutes, then invert onto a cutting board.
