Spicy Kale Tomato Sauce with Brown Rice Pasta

I got some lovely Red Russian Kale from the Dupont Circle Farmer's Market and was inspired to use my kale in a spicy tomato sauce. Any jarred tomato sauce will do and you can add layers of flavor with sauteed onions, garlic, extra herbs (I used dried basil and oregano), and fresh tomatoes. For protein, I added a can of white cannellini beans, which is another current obsession. I happen to LOVE spicy tomato sauce so added almost a 1 teaspoon of red chile flakes. I added the kale at the end after letting the sauce simmer for a good 10 minutes, so I didn't cook all the nutritional value out of the kale. As an added bonus, I purchased the kale two weeks ago, but it was still fresh when I was ready to use it. My pasta was served over brown rice pasta tubes (which were suprisingly good and pasta-like).
