In a large cast-iron skillet, simmer pasta sauce, a few sliced roasted red peppers and some red pepper flakes over a medium campfire. Using a spoon, create a well in the sauce; crack an egg into the well. Repeat with 3 more eggs; season. Simmer until the whites are set and the yolk is cooked to your liking, 12 to 14 minutes. Garnish with torn basil and serve with bread.
