This is what I started with:
Beef Stromboli Recipe:
1 package refrigerated pizza dough
2 Tbsp. Dijon mustard
1/2 pound thinly-sliced deli roast beef
4 oz. sliced Monterey Jack cheese
1/4 cup chopped roasted red peppers (optional)
1 large egg
1 Tbsp. water
2 Tbsp. grated Parmesan cheese
Preheat oven to 375 degrees F. Unroll refrigerated pizza dough. Spread mustard evenly over dough, leaving a 1-inch border all the way around. Top with roast beef slices, then cheese, then roasted red peppers, if using. Roll up lengthwise, jelly-roll style. Place on an ungreased cookie sheet. Beat egg and water. Brush over stromboli. Sprinkle cheese on top of stromboli. Bake 25 to 35 minutes, until golden brown on top and cooked through.
-The only thing that I did differently is that after I laid down the cheese, I added a few more slices of roast beef.
-You could substitute any meat or cheese.
-You could add pasta sauce to it.
This is how I did it:
#1 Preheated the oven to 375.
#2 Opened and rolled out the pizza dough. I threw down some flour so it wouldn't stick.
#3 I spread mustard over the dough.
#4 Laid down the deli-sliced roast beef.
#5 I covered the roast beef with cheese and then added a few more slices of meat.
#6 Next, I rolled the dough up and placed it seam side down on a baking sheet.
#7 I cracked an egg and added water to it
#8 Whisked the egg and rubbed it on the outside of the pizza dough.
#9 I sprinkled Parmesan cheese over the stromboli and popped it in the oven for 35 minutes.
Hope you enjoy!
