Skillet Chicken with Broccoli, Pasta & Parmesan

This is the closest thing to Macaroni Grill's Pasta Milano I've tried. The recipe makes it look more difficult than it actually is, I promise. It's really, really good right after you cook it and the leftovers are fantastic.

2-3 chicken breasts, cut into 1-inch cubes
3 T olive oil
1 onion, minced
4 cloves garlic, minced
1/2 tsp dried oregano
1/4 tsp red pepper flakes
12 ounces penne {I used whole wheat}
4 1/4 cup water
2 1/2 cups chicken broth
4-5 cups broccoli {I used 4 and didn't think it was enough}
{I think I'll add 8 oz. of sliced mushrooms next time}
1/2 cup oil-packed sun-dried tomatoes, rinsed & coarsely chopped
3/4 cup heavy cream
3/4 cup grated parmesan
1 1/2 T lemon juice

Season the chicken with salt & pepper. Heat 2 tablespoons of the oil in a large skillet over medium-high heat. Add the chicken in a single layer and cook for 1 minute without stirring. Stir the chicken and continue to cook until most, but not all, of the pink color has disappeared, 1 to 2 minutes longer. Transfer the chicken to a clean bowl and set aside.

Add the remaining tablespoon of oil, the onion and 1/2 tsp salt to the skillet. Return to medium-high heat and cook until the onion is softened. Stir in the garlic, oregano and red pepper and cook until fragrant, about 30 seconds.

Add the pasta, 3 cups of water and the broth. Bring to a boil over high heat and cook until the liquid is very thick and almost completely absorbed, 12 to 15 minutes, stirring occasionally.

Add the broccoli, sun-dried tomatoes and remaining 1 1/4 cups water. Cover, reduce the heat to medium, and cook until the broccoli turns bright green and is almost tender, 2-3 minutes.

Uncover and return the heat to medium-high. Stir in the cream, parmesan and reserved chicken with any accumulated juices and continue to simmer, uncovered, until the sauce is thickened and the chicken is cooked and heated through, 1 to 2 minutes. Off the heat, stir in the lemon juice and season with salt and pepper to taste. Serve with more parmesan cheese.

I printed this recipe off a blog several months ago but have no idea which one. If I figure it out, I'll update this post to give credit where credit is due.
