Comfort food that is well worth the effort! These delicious rolls contain a filling made with bacon, mushrooms, and FRESH bread slices crumbled-- NO pickle so DH appreciates that. I use sandwich steak, round steak or sirloin and cut into 8 THIN pieces. Serve it with mashed potatoes. Sometimes sirloin is already cut thin which works great! Notice how it is in the oven for 2 hours so you can do something else. Set out your lemon to get it to room temperature. You will need string, cut about 5 inches in length to keep these together. I appreciate puppitypup for noticing that the onions needed explaining.
