Preheat your oven to 400F and line a baking sheet with parchment paper.
Slice the sweet potato into even wedges, toss with a small amount of oil and salt, and roast for 25 minutes until tender.
While potatoes roast, finely mince the onion, garlic, sage, and rosemary.
In a large mixing bowl, combine the ground pork, egg, minced onion, garlic, herbs, sea salt, and black pepper.
Mix the ingredients by hand until just combined and form into four equal-sized patties.
Heat the olive oil in a large skillet over medium-high heat until shimmering.
Place the patties in the skillet and sear for 5 to 6 minutes per side until the exterior is browned and the center is fully cooked.
Remove the patties from the pan and set aside to rest.
In the same skillet, add the chopped kale and apple cider vinegar, sautéing for 2 to 3 minutes until the greens are wilted and bright.
Serve the herb-infused pork patties alongside the roasted sweet potato wedges and sautéed kale.
