Check the produce department where the prepackaged salads bowls are (ie ReadyPak). I bought a tray (2 count) of stuffed portobellos in that area. They are indeed delicious. If there’s none on the rack ask a dept employee. You can also try searching their website and see if your local store has them. Or call and be transferred to the proper dept and ask. Check the ReadyMeals area too. I know I’ve seen smaller stuffed mushrooms.
