Marinated Mushroom Sandwich with Sautéed Greens + Avocado + Egg

Marinated Mushroom Sandwich with Sautéed Greens + Avocado + Egg

Ooey gooey, sloppy sandwiches are made to be devoured all alone. Cooking for one is a rare occasion here at Earthy Feast. I typically make a big batch of something for Mark and I to take to work so we have yummy stuff to munch on and get us through the week. So when I was asked to share a recipe for the ‘cooking for one’ week-long series my first thought was a bowl of cereal, kidding… kinda. My second thought was a super hearty sandwich – one that you can lazily throw together. Everything gets cooked in one pan so the mess stays minimal but the flavor is maximal! Yes! These mushrooms get marinated first with some shallots, a bit of olive oil and white balsamic. Trust me it’s worth the extra step to let them drink up this tasty dressing. Walk the dog, check the mail, put on your comfy pants – then toss them in the pan. Everything will go super fast now – next add the kale to the pan to wilt a bit, then the egg joins the party. If you’re not feeling bread – skip it and just add the avocado on the side. If you think you might need something to soak up all this saucy goodness, may I suggest spreading miso mushroom mayo on top of your toast. It’s delicious.

For the Marinated Mushrooms

10 oz of your favorite mushrooms

1/4 cup olive oil

1/4 cup white balsamic vinegar

1 shallot, finely sliced

1 garlic clove, minced

1 sprig of thyme

1 sprig of rosemary


For the Mushroom Miso Mayo

2 marinated mushrooms

3 tablespoons of your favorite mayonnaise

1 teaspoon miso paste

a spoonful of the marinade sauce with some shallot and onion


For Assembly 

the mushrooms you marinated including that delicious sauce

4 big handfuls roughly chopped kale

1 egg

1 avocado

2 slices of toast



Mix together the ingredients for the mushroom marinade. Clean mushrooms with a towel or soft bristle brush – not water. You want them to soak up this flavorful sauce. Marinate for about 30 min. Place mushrooms, including marinade into pan (leave out the sprigs of herbs). Sauté until golden brown then add the kale to wilt, push it all to the edges of the pan and crack an egg in the center. Cook until preferred doneness. For the miso mushroom mayo combine all the ingredients into your food processor and blend or use your immersion blender. Assemble the sandwich as shown.

    for serious, my friend, those glistening little golden-brown mushies in the pan – oh my. such a lovely combo, grace! and I kind of sort of love cooking for one. namely because it usually means cooking for me and my whims without a care in the world who else wants to eat the world’s most anchovied portion of garlic noodles. 🙂 enjoy it!

    This looks so hearty and delicious! I admire people who cook big pots with the intention of having leftovers for the week – it’s a habit I am trying to ingrain into my cooking patterns. Usually, I’m in the kitchen every evening, making something new … and on the days that I am much too tired or lazy, I order Thai 😉 But a sandwich like this would totally fit the bill for when it’s just me at home, or those evenings when making a large meal is just too much. I especially like the special touch of the marinated mushrooms!

    Gracie, what kind of mushrooms did you use? This is being made by me very soon. Not sure how I missed the original post. THANKS!

      I used shiitake mushrooms here but king trumpet would be good too – if you can find them! I’ve also made this with just plain baby bella mushrooms – that marinade made them taste super yummy!
