Preheat the oven to 425 degrees F. Line a baking sheet with parchment paper. Add the diced potatoes, onion, and bell pepper to the baking sheet. Drizzle over the oil and add the smoked paprika, chili powder, cumin, garlic powder, and salt. Toss everything together until well coated.
Roast for 30-45 minutes, or until the potatoes are tender and starting to get crispy on the edges. Give them a toss halfway through for even roasting.
While the potatoes roast, make the chipotle sauce. Add the mayo, Greek yogurt, chipotle powder, grated garlic, lime juice, salt, and water to a food processor. Blend until smooth. Taste and adjust the salt or chipotle powder to your liking. Set aside.
To make the cottage cheese scrambled eggs, add the eggs and cottage cheese to a blender and blend until smooth and combined. Heat a pat of butter in a skillet over medium-low heat. Pour in the egg mixture and scramble slowly, stirring often. Stir in the shredded cheese just before the eggs are fully set. Season with salt and pepper to taste. Do not overcook, especially if you are planning to reheat the eggs later.
Build your bowls by adding the roasted potatoes as the base, then top with the scrambled eggs. Add any optional toppings you love - sliced avocado, pico de gallo, jalapeños, sour cream, hot sauce, or fresh cilantro. Drizzle the chipotle sauce over the top and enjoy.
