Preheat oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Toss the cubed sweet potatoes with olive oil, smoked paprika, salt, and black pepper on the prepared baking sheet.
Roast the sweet potatoes for 25 minutes, or until fork-tender and slightly browned at the edges.
While potatoes roast, heat a skillet over medium heat and sauté the sliced turkey sausage until browned, then remove from pan.
In the same skillet, add the kale and garlic powder, sautéing for 3 minutes until wilted, then set aside.
Whisk the eggs and milk together in a bowl, then scramble in a non-stick pan over medium-low heat until fully set.
Arrange four airtight meal prep containers and distribute the roasted sweet potatoes, sausage, kale, and scrambled eggs evenly among them.
Allow the contents to cool to room temperature before sealing the lids and refrigerating for up to 4 days.
