A delicious summertime sandwich with crunchy, well-seasoned mushrooms and a tangy, creamy sauce. This reinvented Louisiana classic swaps out the oysters for White Button mushrooms that emulate the texture of the original recipe. The mushrooms are baked instead of fried and the sandwich is loaded with creamy remoulade sauce spread on toasty, buttery hoagie rolls and served with crunchy lettuce.
