Preheat your oven to 375°F (190°C).
In a mixing bowl, combine cream cheese, shredded cheddar cheese, garlic powder, dill weed, and chopped green onions.
Fold in the dill pickle slices gently until they are evenly coated with the cheese mixture.
Using a spoon, fill each pickle slice with the cheese mixture and place them on a baking sheet lined with parchment paper.
Sprinkle the breadcrumb mixture over each filled pickle slice to create a crunchy topping.
Bake in the preheated oven for 15-20 minutes, or until the breadcrumbs are golden brown.
Remove from the oven and let cool slightly before serving. Garnish with extra dill if desired.
