Plan ahead to prepare the dough. Set out the frozen bread dough to rise according to the package instructions. (Set at room temperature in a loaf pan. Then cover with plastic wrap. Allow it to thaw and rise for 5-6 hours.)
Scramble the eggs. In a glass bowl, whisk the eggs well. Heat the butter in a skillet over medium heat. Add the eggs. Use a spatula to move the egg mixture around as it cooks. Continue to do this until the eggs are almost all set.
Assemble the stromboli. Sprinkle with ½ cup shredded cheddar cheese down the center lengthwise. Spoon half of the scrambled eggs over the cheese. Top with half of the turkey sausage. Sprinkle an additional ½ cup cheddar cheese on top.
Close the stromboli. With kitchen scissors or a pizza cutter, make cuts down the long sides of the dough (both sides) about 1 ½” thick and about 3 inches long. Starting at one end, fold one piece of dough across the filing, then fold the first piece of dough on the other side over. Continue in this manner, crisscrossing from one side to the other, until the entire stromboli is covered. Tuck in the ends slightly to seal. Then repeat with the second stromboli.
Serve with ranch, marinara sauce, salsa, hollandaise, or guacamole.
