Preheat your oven to 425°F.
Peel (if desired) and cut the sweet potato into thin fries. In a bowl, toss the fries with canola oil, a pinch of salt, pepper, and finely chopped rosemary.
Spread the sweet potato fries in a single layer on a baking sheet lined with parchment paper. Bake for 20-25 minutes, turning halfway, until crispy and lightly browned.
While the fries are baking, season the bison patty on both sides with salt, pepper, chopped rosemary, and minced garlic.
Heat a skillet over medium-high heat and cook the bison patty for about 4-5 minutes per side, or until it reaches your desired level of doneness.
In a small bowl, toss the arugula with lemon juice, a drizzle of canola oil if desired, and a pinch of salt.
Assemble the plate by placing the herb-seasoned bison patty atop a bed of dressed arugula, with a side of crispy sweet potato fries.
Serve immediately and enjoy the balance of hearty, savory flavors with a refreshing crunch.
