Ingredients

  • 2 Avocados mashed with a fork
  • 4 Oil packed Sundried Tomato halves chopped
  • 1 tsp Oregano
  • ½ tsp Sea salt or Kosher Salt
  • tsp Ground Black Pepper

Caramelized onions

  • 2 tbsp Olive Oil
  • 2 large Yellow Onions sliced
  • ½ tsp Salt
  • ½ tsp Pepper

Instructions

How to make Caramelized onions

  • Heat olive oil in a pan. Once the pan is hot gently transfer the sliced onions to the pan and stir. 
  • Season with salt and pepper and let the onions cook at medium-high heat while stirring occasionally. The onions should cook for 15-minutes or until they are soft, Caramelized in places, and tender. Add extra salt if needed before serving.

Making portobello avocado steaks in the oven

  • Preheat the oven to 400F.
  • Clean the portobello mushrooms and place them with the stem side up in a baking pan. 
    Use a spoon or butter knife to spread a generous layer of red pesto on top of the mushrooms.
  • Cut the avocados in half and carefully remove the stones without cutting yourself. Use a spoon to scrape the avocado meat into a small bowl. Season with oregano, salt, and pepper and use a fork to mash the avocados (there should still be a few lumps left). Next, pour in the chopped sun-dried tomatoes and combine everything.
  • Spread the avocado mix evenly on top of the mushrooms and drizzle with a finish of olive oil.
    Bake the avocados in the oven for 25-minutes or until they are golden on the outside and cooked all the way through to tenderness.
    Serve with a topping of soft onions and enjoy.
