Braised Beef and Tortelloni (Olive Garden Copycat)

I've never actually tried this recipe--it's my best guess to correct my mistakes from last time I tried this dish

• Ready In: 3 hrs
• Serves: 2-4

Ingredients

• 3  tablespoons olive oil
• 1 -2  lb boneless beef short rib (or similar tough cut of beef)
• 1  garlic clove, minced
• 1  tomatoes, diced
• 6  ounces fresh mushrooms, sliced
• 8  ounces marsala wine
• 1⁄4 cup flour
• 1  tablespoon  italian seasoning
• 1 -2  lb  asiago-filled  tortellini, boiled

Directions

1. Heat oil on high heat in a large nonstick pan.
2. Toss short ribs in flour, add to pan, and sear on all sides.
3. Reduce heat to low and add garlic; cook and stir for about 1 min.
4. Add tomato, mushrooms, Marsala wine, and Italian seasoning one at a time, allowing about 1-2 min between each for liquid to evaporate.
5. Cover pan and braise for 3 hr or until very tender, checking and stirring every 30 min to make sure liquid has not evaporated away (add more Marsala if liquid evaporates).
6. Increase heat to medium high and heat thoroughly.
7. Serve over tortelloni.
