Start your day with these low calorie, avocado egg stuffed mushrooms. This high protein, low carb, nutrient packed breakfast will keep you full all day.

If I’m not sautéing eggs for the top of my mushrooms, I’m putting the eggs inside my mushroom!

I love this twist on my traditional breakfast of eggs and mushrooms. Stuffed mushrooms, with all the delicious breakfast ingredients I use like egg whites, a whole egg, avocado and tomato, are the perfect way to have a little variety in my morning (see my 19 low calorie egg ideas here)

I realize mushrooms, like portobellos, are disliked by many people. I didn’t become a fan of mushrooms until after I turned 40. But now, I rarely have a day without eating them!

Why you should eat mushrooms

I first decided to give them a try during my obsession with Dr. Joel Fuhrman. One of my favorite books, Super Immunity, he introduces the idea of eating GBOMBS every day. GBOMBS are:

  • Greens
  • Beans
  • Onions
  • Mushrooms
  • and Berries

Dr. Fuhrman says, “White, cremini, Portobello, oyster, shiitake, maitake, and reishi mushrooms all have anti-cancer properties—some are anti-inflammatory, stimulate the immune system, prevent DNA damage, slow cancer cell growth, cause programmed cancer cell death, and inhibit angiogenesis.”

In addition, the Mushroom Council promotes mushrooms as a way to maintain a healthy weight. (The mushroom council has LOADS of resources here!)

How can you argue with that!? Since learning the benefits of mushrooms, I’ve tried to incorporate them more into my diet. If you still aren’t on the mushroom bandwagon, the first time I found them delicious was sautéed in butter and loaded onto a burger. From there, I was hooked!
