Pour in the can of fire-roasted tomatoes—the full can, do not drain the juices. Mix the vegetables, then let them simmer for 5 minutes, stirring occasionally.
Using a spoon, create four divets in the tomato mixture. Crack the eggs gently into each divet. Use the spoon to carefully scoop a little bit of the tomato sauce mixture on top of the egg whites.
Sprinkle the shakshuka with a dash of salt and pepper, then move the skillet to the oven.
Bake for 10 minutes. The eggs may still jiggle a bit as you take them out, this is okay! You don't want to overcook them.
Sprinkle with feta cheese and chopped parsley, if desired. Serve with toasted pita bread in bowls.
