Preheat oven to 375 degrees Farenheit. Put about 1Tbsp. butter on a sheet pan (I lined the sheet pan with nonstick aluminum foil first-worked great!). Put pan in preheated oven and melt butter. Thinly slice a pear that you've cored. Take pan with melted butter out of oven, put tortilla on butter, then flip over so bottom is greased. Put sliced pear on the tortilla, dot about a teaspoon butter on pear in little bits, sprinkle a little sugar on pear. Bake in preheated oven for about 10 minutes, until the pear is cooked through and the tortilla is lightly browned around the edges. Remove from oven, cut into wedges and enjoy while still warm.
