This deeply flavored portobello melt makes a hearty fall sandwich filling. It's no wonder our members voted this a favorite! Smarts: This is a great recipe to double - bake off all the melts and then freeze for future use.
Spread kale leaves onto a sheet pan. Use two pans if they’re too packed on one. Toss with olive oil and then bake for 8 to 12 minutes until leaves are crispy. If they start to brown too much at the edges, they’re definitely done! Sprinkle with salt right out of the oven.
Heat a skillet over medium-high heat. Add cooking oil and then place portobellos cap side up. Sear for 2 to 3 minutes and then flip. Lightly salt and pepper and then spoon in pepper and cheese filling into mushrooms. Cover with foil and cook until mushroom is tender, 5 to 7 minutes.
Warm up buns in the oven. Assemble sandwiches with stuffed mushrooms, tartar sauce, and sliced tomatoes. Enjoy with kale chips!
