Before starting, wash and dry all produce. Add 10 cups water and 2 tsp salt to a large pot. (NOTE: Use same for 4 ppl.) Cover and bring to a boil over high heat.

While water comes to a boil, heat a large non-stick pan over medium-high heat. When hot, add 1 tbsp oil (dbl for 4 ppl), then onions and Italian Seasoning. Cook, stirring occasionally, until softened, 2-3 min. Add beef. Cook, breaking up beef into smaller pieces, until no pink remains, 4-5 min.\*\* Season with salt and pepper.

Add broth concentrate, crushed tomatoes and half the vinegar to the beef. Season with salt and pepper. Reduce heat to medium. Simmer, stirring occasionally, until sauce starts to thicken, 10-12 min. While the sauce simmers, add rigatoni to the pot of boiling water. Cook, stirring occasionally, until tender, 11-12 min.

While rigatoni cooks, halve tomatoes. Finely chop olives. Roughly chop parsley. Combine tomatoes, olives, parsley, remaining vinegar and 1 tbsp oil (dbl for 4 ppl) in a small bowl. Season with salt and pepper.

When rigatoni is tender, reserve 1/3 cup pasta water (dbl for 4 ppl). Drain rigatoni, then return to the same pot over medium heat. Add sauce and reserved pasta water to the pot. Stir together, until rigatoni is fully coated. Season with salt and pepper.

Divide beef ragout between bowls, then top with olive tapenade. Sprinkle Parmesan over top.
