Sauté olive oil, carrot, onion and celery in large skillet on Medium-High heat. Cook 4-5 minutes until carrots soften and onions/celery become translucent. Add ground beef and Italian sausage to the skillet. Stir in garlic. Reduce heat to Medium; cook until meat is cooked through, browned, and in small pieces. Discard any grease.

Stir wine, salt, oregano, Italian seasoning and bay leaf into meat mixture. Cover skillet, reduce heat to LOW; simmer 8-10 minutes, stir occasionally. Remove skillet from heat; uncover. Remove/discard bay leaf; let meat filling cool COMPLETELY (approx. 30-35 minutes).

When mixture has cooled, add eggs and Parmesan. Stir well, until completely incorporated. Mixture should hold together enough to form a pliable ball. TIP: Have a food processor? Use it for this step. Pulse meat mixture a few times until pureed. It should still be able to form a ball (if not, add 1-2 T. more Parmesan).

Need A Simple Recipe For Pasta Dough? While meat filling cools, you can prepare pasta following this recipe. Place 3 eggs and 2½ cups of all purpose flour in a large mixing bowl (if making by hand) OR in the bowl of a stand mixer. Combine eggs/flour until they're well-blended. Too wet? Add a bit more flour. Too dry? Add a bit more water. Place dough on a lightly floured surface and firmly knead until it comes together and has a consistent texture/color throughout. Form into a mound; cover with a damp towel (or wrap tightly in plastic wrap), and let dough REST for 15 minutes.

Using a Pasta Rolling Machine Or Attachment?: Unwrap dough; divide into 4 pieces. Roll 1 piece at a time (keep remaining pieces covered with damp towel). Use a pasta attachment OR manual pasta machine to roll dough into ¼" thick, 7"-8" long sheets (approx. 3-4" wide). Lay pasta on lightly floured surface; keep covered. **Follow manufacturer instructions for best results.**

Making Pasta Dough By Hand?: If rolling the dough by hand, use a rolling pin. Roll each piece of dough into ¼" thick, 3-4" wide, 7-8" long sheets. Place pasta sheets on a lightly floured surface; cover with a damp towel.

Method #1- Use a ravioli form. Using this method, you will lay a thin layer of a pasta dough sheet over the form, then scoop the meat filling into the "cups". Place another thin pasta dough sheet on top, to cover, then cut and firmly seal.** Use manufacturer's instructions for best results.**

Method #2- Lay a long pasta dough sheet on lightly floured work surface. Scoop small portions (1 rounded teaspoon) of meat filling onto the center of the dough, leaving 1"between each mound and leaving dough around all edges of the filling. Lay a second sheet of pasta on top. Press outside edges firmly to completely seal, then cut into individual raviolis, and seal each one firmly. removing as much air as possible before the final edge is sealed.  

You may need to cook ravioli in two batches, depending on the size pan you use. Bring a large saucepan of water and a pinch of salt to a boil, on HIGH heat. Once fully boiling, carefully add ravioli. Cook for 6-8 minutes; drain water from pan.

After draining, transfer ravioli to plates; serve immediately, topped with marinara or meat sauce (heated). If desired, sprinkle ravioli with additional Parmesan cheese and/or fresh chopped parsley). Enjoy!
