Preheat the oven to 425°F (220°C). Add 1 pound sweet potatoes and 1 can black beans to a baking sheet. Toss with 2 tablespoons olive oil, 2 tablespoons taco seasoning, 1 teaspoon smoked paprika, ½ teaspoon salt, and black pepper. Spread into one layer and bake for 25 to 30 minutes, or until the sweet potatoes are tender and lightly browned.
In a small bowl, whisk together ¾ cup Greek yogurt, 2 tablespoons lime juice, 1 tablespoon olive oil, ½ small clove garlic (grated), ¼ teaspoon salt, and ¼ cup fresh cilantro (chopped). Stir in 2 to 4 tablespoons water until the sauce is smooth and easy to drizzle. Taste and add more lime or salt if needed.
Divide the lettuce between bowls. Top with the roasted sweet potatoes and black beans. Add cottage cheese, avocado, and corn, or your favorite veggies.
Drizzle with the cilantro lime sauce and finish with pickled onions, pickled jalapeños, or crushed tortilla chips for extra flavor and crunch. For a heartier bowl, add cooked rice, quinoa, or your favorite grain. Serve right away.
