Vegan Nachos Verdes

Preheat the oven to 350°F. Line 2 baking sheets with parchment paper. 2. Spread the tortilla pieces on the baking sheets, and bake for 20 to 25 minutes, or until crisp. Remove from oven and set aside to cool for a few minutes. Leave oven on. 3. Combine the lima beans, corn, onion, garlic, cumin, and oregano in a saute pan with ½ cup of water. Cover pan and cook for 10 minutes, until the beans are tender. Add salt to taste. 4. To make the tofu sour cream, combine the tofu, spinach, lemon juice, vinegar, salt, and mustard in a blender; blend to a smooth paste. 5. Arrange half of the baked tortilla chips in the bottom of a 9x13-inch baking dish. Spread half of the beans mixture over the chips. Dollop one-third of the tofu sour cream and salsa over the top, then sprinkle with half of the scallions and cilantro. Repeat with a second layer of chips, beans, tofu sour cream, salsa, scallions, and cilantro. 6. Bake for 20 minutes, or until heated through. 7. Remove nachos from oven, and top with remaining salsa and tofu sour cream, plus lettuce, avocado, and jalapeño (if using). 8. Serve immediately.
