Preheat your oven to 400°F (200°C).
Place the diced sweet potatoes on a baking sheet, drizzle with 1 teaspoon of avocado oil, and roast for 20 minutes until tender.
In a medium mixing bowl, combine the ground beef, dried sage, dried thyme, garlic powder, onion powder, crushed red pepper flakes, sea salt, and black pepper.
Mix the spices into the meat thoroughly using your hands, then form into three equal-sized circular patties.
Heat the remaining 1 teaspoon of avocado oil in a cast-iron skillet over medium-high heat.
Place the patties in the hot skillet and sear for 4 to 5 minutes per side until a golden-brown crust forms and the meat is cooked through.
Remove the patties from the pan and set aside; immediately add the fresh spinach to the same skillet, sautéing for 1 minute until just wilted.
Plate the savory beef patties with the roasted sweet potatoes and sautéed spinach for a balanced, protein-packed meal.
