Heat oven to 400 degrees F and lay prosciutto out on a parchment-lined baking sheet. Bake for 6 minutes, flip and bake another 5-6 minutes.
Remove to a plate to cool and then crumble. Heat to 450 degrees F and bake pear slices with a drizzle of olive oil for 10- 15 minutes. Flip when they start to brown and cook another 5 minutes. Set aside to cool.
Heat oven to 350 degrees F.
Using a hand mixer, combine cream cheese, sour cream and mayonnaise with seasonings.
Add Treasure Cave Crumbled Blue Cheese and fold to combine.
Add two-thirds of the pears and prosciutto and fold again. Place in a baking dish or deep-dish pie dish (8x8 inches) and bake at 350 degrees F for 30 minutes.
Top with remaining pears, prosciutto, additional Treasure Cave Crumbled Blue Cheese and fresh herbs. Bake for another 5-10 minutes or until bubbling.
Serve with crostini (see step 9 if you want to make them yourself).
To make crostini, slice a baguette thinly and layer on a baking sheet. Brush with oil or butter. Put the baking sheet under broiler and let slices get toasty. You can flip them to toast both sides if desired.
