Preheat the oven at 350 degrees f

Lightly brush avocado oil on portobellos and season.

Then place mushrooms stem side up on a greased baking sheet.

Very gently crack open the eggs and carefully place one inside each mushroom, right where the stem was.

Sprinkle with cherry tomatoes, thyme leaves, and sea salt & pepper to taste.

Bake for 15-20 minutes in your preheated oven until the eggs are cooked to your liking.
