01 - Heat basil pesto in a non-stick skillet over medium heat until aromatic and sizzling.
02 - Crack eggs directly into the hot pesto. Cook for 2 to 3 minutes, until the whites are just set and yolks remain runny, or to preferred doneness.
03 - While eggs cook, toast the bread slices in a toaster until golden brown.
04 - Transfer each cooked egg onto a slice of toasted bread, drizzling remaining pesto from the pan over the top.
05 - Garnish with grated Parmesan, red pepper flakes, or fresh basil as desired. Serve immediately.
