Trim the excess skin from the underside of the mushroom.
Mix the cream cheese, cheddar cheese, garlic powder, paprika, cilantro stems, and diced jalapeños in a medium bowl until well combined.
Place the chips in a small bowl and smash into a large crumb. Add the parmesan and combine well.
Using a teaspoon, fill the inside of the mushroom cup with the cream cheese mixture. Smooth off the top.
Wrap a strip of bacon around each mushroom and secure it with a toothpick.
Top each mushroom with a slice of pickled jalapeño.
Top each mushroom with some potato chips and a sprinkle of BBQ seasoning.
Place the mushrooms in a grill basket and then into the grill.
Close the lid and cook for 20 - 25 minutes or until the bacon is crispy and golden to your liking.
Notes
Bacon - you want a good mushroom-to-bacon ratio, so you may have to trim your bacon slices to suit. Mine were a thin, streaky cut. The length was good but too wide, so I cut each strip in half lengthways, which gave me two strips, so I only needed 12 strips.Grill basket - If you use a grill basket, don't overcrowd it; the bacon will not crisp as well.
