Cut one potato into small, even cubes so the pieces brown at roughly the same rate. Season them with salt and pepper, coat them lightly with oil, and add a teaspoon of chili powder if you want another layer of chile flavor.
Bake the potatoes at 400°F for 20 to 25 minutes. Turn or stir them at about the 15-minute mark, then continue roasting until the edges have browned and the centers are cooked through. Starting here gives you time to make the salsa and other fillings while the oven does most of the work.
