Preheat your oven to 425°F. Place the bell peppers on the baking sheet and drizzle with oil. Season with salt and pepper and toss to coat.
Roast the bell pepper strips for 10 minutes. The pieces should be slightly charred and fork-tender when done.
Notes
Your roasting time will vary depending on the thickness and size of your strips of bell peppers. Check your oven at 10 minutes and adjust accordingly. ½-inch slices of bell pepper will roast in about 10 minutes. 1-inch slices will roast in closer to 20 minutes.
