Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Cut the chicken breast into bite-sized nugget pieces and dice the sweet potato into small half-inch cubes.
Toss the sweet potato cubes with half of the olive oil and a pinch of sea salt, then spread them onto one side of the prepared baking sheet.
In a small shallow bowl, whisk the egg until smooth. In a second shallow bowl, combine the almond flour, garlic powder, smoked paprika, sea salt, and black pepper.
Dip each chicken piece into the egg wash, then dredge in the almond flour mixture until fully coated.
Place the coated nuggets on the other side of the baking sheet and drizzle the remaining olive oil over the top.
Bake for 18 to 20 minutes, flipping the nuggets halfway through, until the chicken is cooked through and the sweet potatoes are fork-tender.
Place the mixed greens in a bowl and top with the hot baked nuggets and roasted sweet potatoes to serve.
