Smoked Cheddar Shells and Cheese with Kielbasa

Smoked Cheddar Shells and Cheese with Kielbasa(serves 4)

3 tbsp butter
3 tbsp flour
2 c milk
1 1/4 c grated mild cheddar cheese
1/2 c grated smoked cheddar cheese
1/2 box shell pasta (I used Eden Organic Veggie Shells)
2 Kielbasa links
olive oil

1. Cook shells according to package directions, drain and rinse.
2. Cut kielbasa into "non-chokable" sized chunks.
3. Heat a little olive oil in a medium saute pan over medium heat. Cook kielbasa chunks until heated through. (About 5 minutes)
4. Melt butter in a medium saucepan over medium heat.
5. When melted, add flour, stirring constantly for about 1 minute creating a roux.
6. Whisk in milk, cook for 3 minutes (stirring constantly).
7. Add the cheeses, and stir until smooth.
8. Combine the cheese sauce, shells and kielbasa. Serve!

This one is seriously yummy.
