Place pasta in Multipurpose Steamer. Stir in water. Cover; microwave on high until al dente, about 12 min. Drain.
While pasta is cooking, dice carrots. In Wok, heat oil over medium-high heat. Add carrots; sauté until tender-crisp, about 3 min.
Add tomato paste. Crumble in beef. Cook until meat is cooked through, 4–5 min. Using a Ground Meat Separator, stir and break up chunks halfway through cooking.
Stir in tomatoes, topper blend, and Worcestershire sauce. Simmer, stirring occasionally, for 5–6 min to let flavours blend. Reduce heat as needed.
Add pasta; stir to combine, then spoon into bowls. For a thicker sauce, remove from heat; let rest 2–3 min before serving. Shake on additional topper blend, to taste.
