In a skillet pan add olive oil and garlic cloves crushed with a flat side of the knife.
If you prefer a stronger garlic taste, chop it finely.
Let simmer for a minute or two without letting the garlic burn.
Add fresh tomatoes previously washed, cleaned from the seeds and cut in small cubes.
As an alternative add ½ cup diced tomatoes from the can.
Let tomatoes cook until soft.
Beat eggs with a pinch of salt and chopped parsley.
Pour the eggs over the garlic tomato mix. In a minute, remove excess oil (or salt) from the anchovies and place them over frittata going around the clock.
Place frittata in a preheated to 375F oven for 10-15 minutes to finish cooking.
Grind some pepper and garnish with fresh parsley.
Notes
Do not exaggerate with salt in the eggs. Anchovies are already salty enough and you risk the over-salting.
