Here’s a delicious, decadent and devilishly fast beef steak sandwich. We can’t recommend the tender beef enough, it’s mouth-watering with mushrooms and a melty Cheddar on top. The hint of saucy sweetness comes from the onion chutney tossed through the mushrooms. It will be love at first bite.

Produced in a facility that processes eggs, milk, fish, peanuts, sesame, shellfish, soy, tree nuts, and wheat.
