- Heat oven to 375°F In 10-inch nonstick skillet, cook bacon over medium heat 2 minutes. Add ground beef and onion; cook, stirring occasionally, until beef is thoroughly cooked; drain if necessary. Stir in pickles and ranch dressing.
- Unroll dough and separate each can into 4 rectangles; place on ungreased cookie sheet. Press each into 7 x 4-inch rectangle, firmly pressing perforations to seal.
- Spoon about 1/3 cup ground beef mixture onto one end of each rectangle. Top each with tomato slices and 1 piece of cheese. Fold dough over filling; press edges with fork to seal (sandwiches will be full). Brush tops with egg.
