Tuscan Sausage and Pepper Spaghetti

Heat 4 tsp oil in a large pan over medium-high heat. Add onion, bell pepper, and half the Tuscan heat spice. Cook, tossing, until lightly softened, 3-4 minutes.

Remove sausage from casings. Add sausage and a large drizzle of oil to pan with veggies, breaking up meat into pieces. Cook, tossing occasionally, until sausage is cooked through and browned at edges, about 5 minutes.

Once water boils, add spaghetti to pot. Cook, stirring occasionally, until al dente, 9-11 minutes. Carefully scoop out and reserve 3 cups pasta cooking water, then drain.

Meanwhile, once sausage is browned, add tomatoes to pan. Season with salt, pepper, and remaining Tuscan heat spice, then give everything a stir. Bring to a boil, then lower heat and let simmer until pasta is done. After you've drained spaghetti, stir 2 cups pasta cooking water and stock concentrates into pan. Continue simmering until slightly reduced, about 2 minutes.
