Adjust racks to top and middle positions and preheat oven to 450 degrees. Wash and dry produce.
Dice potatoes into 1⁄2-inch pieces. Toss on one side of a baking sheet with a drizzle of oil, salt, and pepper.
Roast on middle rack until lightly browned and tender, 20-25 minutes total. (You’ll add more to the sheet after 10 minutes.)
