In a medium skillet over medium heat, melt 2 tablespoons butter. Add sliced pear and cook on low for about 2 minutes, stirring occasionally. Add honey and a pinch of salt, and cook until they’re slightly mushy and lightly browned. Remove from the pan and set aside.
Return the empty skillet to the stove, add sliced mushrooms and saute until they soften and release their juices (2-3 min). Remove from heat and set aside.
Preheat oven to 400 F. Lightly brush the pizza crust with the olive oil. Sprinkle the crust with the mozzarella cheese. Spread the pears and mushrooms all over the pizza and cover them with the prosciutto. Then crumble the blue cheese over top.
Bake for 10-12 min (or according to package instructions), until crust is slightly golden and the cheese is bubbling. Remove from oven and top with fresh arugula. Cut into pieces and serve. Enjoy!
