1. Brown the ground beef and with the onion and garlic over medium-high heat.
2. Cook noodles to al dente, drain.
3. While the beef and noodles are cooking, add tomatoes to a food processor. Add parsley, basil and oregano (or an Italian seasoning) to your liking – about 1 teaspoon each. Blend until just small chunks of tomato remain.
4. Add tomato paste and mix.
5. Add meat and tomato sauce to the noodles.
6. Preheat oven to 350.
7. Combine melted butter and garlic salt.
8. Roll out the pizza dough into a rectangle (mine was more circular!) and cut into 4 squares.
9. Brush each square with garlic butter.
10. Place a heaping spoonful (almost 1/2-2/3 cup) of spaghetti with sauce on one half of each square.
11. Add ¼ cup of mozzarella cheese and sprinkle on olives. Love these for a salty taste and for more color!
12. Fold dough over the spaghetti forming a triangle or half-moon shape and seal edges together (press together with a fork or twist together).
13. Bake for about 20 minutes or until the calzones are golden. Remove from oven and brush with butter. Serve with additional spaghetti sauce.
If you have extra spaghetti & meat mixture, make a great leftover meal by melting mozz cheese on top and adding a few olives!
