Preheat your oven to 400°F (200°C).
Toss the diced sweet potatoes in olive oil, garlic powder, black pepper, and salt.
Spread the sweet potatoes on a baking sheet in a single layer.
Roast in the preheated oven for about 20-25 minutes or until the sweet potatoes are tender and slightly caramelized, stirring halfway through.
In a serving bowl, add 1/2 cup roasted sweet potatoes then assemble to your liking of savory or sweet bowl toppings.
