Penne with Tomatoes, Pesto & Artichokes (& Sausage)

I had quite a challenge on my hands Friday night. My kids requested "noodles" for dinner (surprise, surprise), I had sausage I wanted to try, and a bottle of pesto I felt inclined to use. The problem: I had no real recipe to cook by. I could have thrown a few things together, but thought I'd go to this trusty site: www.epicurious.com Of course, I found a recipe, and it was good--as usual.

Penne With Tomatoes, Pesto & Artichokes
(Bon Appetite, July 1998)
http://www.epicurious.com/recipes/food/views/PENNE-WITH-TOMATOES-PESTO-AND-ARTICHOKES-5454

1 6- to 7-ounce jar marinated artichoke hearts, drained
3 tablespoons oil reserved
1 large onion, chopped
3 large garlic cloves, chopped
1 28-ounce can diced tomatoes in juice
1/2 cup purchased pesto
12 ounces penne pasta, freshly cooked
1/3 cup grated Parmesan cheese
Additional grated Parmesan cheese

Heat 3 tablespoons oil reserved from artichokes in heavy large pot over medium-high heat. Add onion and garlic and sauté until onion is tender, about 7 minutes. Add tomatoes with their juices and artichokes. Simmer until sauce thickens slightly, about 8 minutes. Add pesto; simmer 1 minute longer.
Mix in pasta and ­ cup cheese. Season pasta with salt and pepper.Transfer pasta to large bowl. Serve, passing additional Parmesan separately.

My notes on this recipe are:
I only used a 14oz. can of diced tomatoes and therefore cut the pesto down to about 1/3 c.--there was still enough sauce to coat the pasta, but not be drenched in it.
I also added sausage. I was introduced to this yummy chicken, spinach & fontina cheese sausage by my friend Tamara...it is "Han's All Natural Gourmet Sausage". You can get it at Costco. It is precooked but can be grilled, broiled, microwaved, sauteed, etc. when you are ready to eat it. I sliced mine into 1/4 inch pieces and sauteed it with the onion and garlic in this recipe. Sidenote: Marc ate the other sausage for dinner the next night on a hot dog bun with catsup and mustard and loved it that way, too. It's good stuff!
