Crack eggs into pan over medium heat. Stir until partially cooked, then add in a splash of milk.
Mix in kale or spinach and cook.
Add in 1/2 of lemon basil walnut pesto and stir to combine. It is recommended to eliminate the lemon, especially if having for leftovers. The lemon flavor is accentuated in the leftovers.
Continue to stir until eggs are thoroughly cooked. Top with mozzarella cheese, if desired.
