1 Lightly grease two 9x 1 1/2-inch round baking pans or one 12- or 13-inch pizza pan. Set aside.
2 Prepare hot roll mix according to package directions for basic dough, using the 1 egg and substituting the 2 tablespoons olive oil for the margarine called for on the package. Knead dough; allow to rest as directed. If using round baking pans, divide dough in half; roll each half into a 9-inch round. If using a pizza pan, roll dough into a 12-inch round. Place in prepared pan(s).
3 In a skillet cook onion and rosemary in the 3 tablespoons oil until onion is tender. With fingertips, press indentations every inch or so in dough round(s). Top dough evenly with onion mixture. Cover; let rise in a warm place until nearly double in size (30 to 40 minutes).
4 Bake in a 375° oven for 15 to 20 minutes or until golden brown. Remove from pan to a wire rack; cool.
