In a large bowl, stir together all of the creamy ingredients (sour cream, cream cheese, parmesan, and half the mozzarella).

Add in the spinach and Knorr soup mix. Stir well with a wooden spoon until combined. If you’re making this at home before your trip, store it in an airtight container in your cooler.

Lay out two large sheets of aluminum foil. Spoon the cheese mixture into the center, top with reserved mozza and fold it up, crimping the edges tightly so no melty goodness escapes.

Place the packet near the hot coals (not directly in the flames) and let it cook for about 20-25 minutes, until everything is warm and bubbly. You can also place it on a campfire grill, barbecue grill or cook it in a cast-iron skillet if you prefer.
