Preheat your oven to 400°F (200°C).
Peel and dice the sweet potato into 1/2-inch cubes.
Toss the sweet potato cubes with 0.25 tbsp of olive oil and the sea salt on a baking sheet.
Roast for 18-20 minutes until the potatoes are tender and golden brown.
While potatoes roast, mince the garlic clove and pat the shrimp dry with a paper towel.
Heat the remaining 0.25 tbsp of olive oil in a skillet over medium-high heat.
Add the shrimp, minced garlic, red pepper flakes, and black pepper to the pan.
Sauté the shrimp for 2-3 minutes until they are pink and opaque, then remove from heat.
Place the roasted sweet potatoes in a bowl and top with the spicy shrimp.
Add the chilled sauerkraut to the side of the bowl and serve immediately.
