Mediterranean Tuna-Noodle Casserole

My church regularly sends out emails for help with meal requests and I try to help out whenever possible. A recent request came my way and noted "no chicken or shellfish." I assumed the rest of the meals might be red meat heavy so I looked for alternatives and found a delicious Martha Stewart recipe for Mediterranean Tuna-Noodle Casserole. The recipe makes enough for two dishes so it was perfect to make one for us and one for someone else's freezer. It earned our seal of approval and a spot on our meal rotation so I thought I'd pass it along.

1/3 cup olive oil, plus more for baking dishes
Coarse salt and ground pepper
1 pound wide egg noodles
2 red bell peppers (ribs and seeds removed), thinly sliced
1/2 cup all-purpose flour
5 cups whole milk
4 cans (6 ounces each) tuna in olive oil, drained*
1 can (14 ounces) artichoke hearts, drained and thickly sliced
5 scallions, thinly sliced
1/2 cup finely grated Parmesan

Preheat oven to 400 degrees. Lightly oil two 8-inch square (or other shallow 2-quart) baking dishes. In a large pot of boiling salted water, cook noodles until 2 minutes short of al dente; drain, and return to pot.

Meanwhile, in a 5-quart Dutch oven or heavy pot, heat oil over medium. Add bell peppers; season with salt and pepper. Cook until crisp-tender, 4 to 6 minutes. Add flour and cook, stirring, 1 minute. Gradually add milk, stirring until smooth. Cook, stirring occasionally, until mixture comes to a simmer.

Remove from heat; add mixture to noodles in pot, along with tuna, artichoke hearts, and scallions. Season with salt and pepper, and toss. Divide between prepared baking dishes, and sprinkle with Parmesan. Bake until golden and bubbling, about 20 minutes.

*Instead of four cans in oil, I used two in oil and two in water.
