Preheat a Lodge 5 Quart Cast Iron Dutch Oven over medium heat. Add the 3 tbsp Olitalia I Dedicati Pizzolivm Extra Virgin Olive Oil to warm.
Add the onion, carrots and Cattleman’s Grill California Tri-tip Seasoning. Cook, stirring occasionally until the onions are translucent.
Add the thyme and garlic. Cook for 30 seconds. Add the wine and cook until it is nearly all the way reduced.
Add the frozen peas, cubed leftover beef, green onions and beef stock/water. Cover with a lid. Bring to a simmer. Cook until the beef is falling apart.
Mix all ingredients for the dumplings. Uncover the dutch oven. Drop a couple of tablespoons at a time of the dumpling dough into the simmering soup.
Continue cooking until the dumplings are firm and cooked through.
