Preheat your oven to 425°F (220°C).

In a mixing bowl, combine the diced sweet potatoes with olive oil, garlic powder, paprika, salt, and pepper. Toss well until all pieces are evenly coated.

Spread the seasoned sweet potatoes in a single layer on a baking sheet. Roast for 25-30 minutes, stirring halfway through.

While the sweet potatoes roast, season the sirloin steak bites generously with salt and pepper.

Heat a skillet over medium-high heat and add a splash of olive oil. Add the steak bites, cooking for 3-4 minutes until they are browned.

Remove the skillet from heat and let the steak bites rest for a few minutes.

Plate the steak bites alongside the roasted sweet potatoes and garnish with fresh parsley.
