Roasted Mushroom Sandwich with Horseradish Aioli
Layers of roasty mushrooms, havarti, lemony arugula, and an easy homemade horseradish aioli make this mushroom sandwich a WINNER. A saucy, salty, hefty masterpiece!
How To Make This Mushroom Sandwich
1
Roast the mushrooms.
Toss the mushrooms with olive oil and a hefty sprinkle of seasoning (I use Cajun seasoning). Roast ’em up till they’re golden, chewy, and delicious.
2
Make that horseradish sauce.
Oh man, it’s so good. Mix your mayo, garlic, lemon, and horseradish together. Season with salt.
3
Toast and split the bread.
Would highly recommend the caramelized onion focaccia from Trader Joe’s for this one.
4
Layer your sandwich.
My layers: pesto rosso (also from Trader Joe’s, and optional), mushrooms, havarti cheese (melted for funs), arugula, and horseradish sauce on top.
5
You’re Done! Yum.
Devour and enjoy.
