Prep the Potatoes: Preheat the oven to 425℉ (218°C). Line a sheet pan with parchment paper and spray with olive oil spray. Wash your sweet potatoes. On a cutting board, use a sharp knife to cut them into 1 inch cubes. In a large bowl or directly on the baking sheet, coat the sweet potato cubes with olive oil, kosher salt, pepper, garlic powder, and smoked paprika.
Roast the Potatoes: Add the sweet potatoes to the baking sheet in a single layer and baked in the preheated oven for 25-30 minutes. Oven times will vary.
Make the Creamy Elote Dressing: while the sweet potatoes are baking, make the dressing by combining the Greek yogurt, olive oil mayonnaise, lime zest, lime juice and seasonings. Mix well to combine with a whisk or spoon.
Make the Street Corn Mixture: If using fresh ears of corn, cook it using your preferred cooking method and remove fresh corn kernels from the cob with a sharp knife. Remove the pulp and seeds from the jalapeno. Chop the jalapeno, red pepper, red onion, and cilantro. To assemble the salad, add the corn, bell pepper, cilantro, red onion, cotija cheese, and jalapeno to a large bowl. Add about half of the dressing.
Cook the beef: Heat a large skillet on medium heat. Add olive oil until heated. Add the ground beef and break apart the beef with a wooden spoon or masher. Cook for 2-3 minutes until the beef starts to brown and then add the seasonings, water, and tomato paste. Continue to cook until the beef is cooked through, about 5-7 minutes.
Assemble the bowls: add the sweet potatoes, beef, and street corn salad, and romaine (optional) to a bowl. Top it with more dressing and your favorite toppings!
Hint: meal prep in advance by making the corn salsa and dressing and roasting the potatoes ahead of time so all you have to do when dinner rolls around is cook the beef and assemble everything.
