These panko crusted portobello mushrooms have been one of our community's favorites and we're bringing it back with a summer salad! Smarts: If you don't want to heat up your oven, just fire up your grill. Place portobellos onto foil and bake using same instructions.
Crust - Chop parsley. Melt butter in the microwave (~1 minute should do). Mix butter with Dijon, maple syrup, soy sauce, panko, and parsley. (Can be done up to 3 days ahead)
Shallots - Slice. (Can be done up to 4 days ahead)
Line sheet pan with foil and brush with some cooking oil. Place portobellos top-side down and then divide and spoon crust onto mushrooms. Bake for 10 to 14 minutes.
While portobellos are cooking, whisk together vinegars, maple syrup, and oil. Season to taste with salt & pepper.
When portobellos are ready, toss vinaigrette with greens, shallots, corn kernels, peaches, nuts, and queso fresco. Enjoy together!
