(Lite) Creamed Spinach

I love, love, love creamed spinach but don't like all the calories that go along with it!  I found a recipe here that called for low fat milk and fresh spinach (I don't like frozen).  This turned out delicious and the best part is that it's done in minutes!  A great side dish for a weeknight meal!!

Ingredients:
2 tsp Extra Virgin Olive Oil
1/4 cup mined shallot, or red onion
10 oz fresh spinach, tough stems removed
1 tbsp butter (I used margarine)
1 tbsp all-purpose flour
1/2 c low fat milk (I used 2%)
1/8 tsp ground nutmeg
Salt & Pepper to taste
2 tbsp fresh grated Parmesan cheese

Directions:
Heat oil in a large non-stick skillet or dutch oven over medium high heat. 
Add shallot (or onion) and cook, stirring until fragrant, about 30 seconds.
Add spinach and cook, stirring until just wilted, about 2 minutes
Heat butter in a small sauce pan over medium heat.
Add flour & cook, stirring until smooth and bubbly, about 30 seconds
Add milk, nutmeg, salt & pepper.  Cook whisking constantly until thick, about 1 minute.
Stir the spinach into the sauce. 
Sprinkle with Parmesan cheese & serve.
