Sweet Italian sausage with white beans and chard over pumpkin polenta

This is divine!!!   Serves 2 but can easily be doubled.

1/2 cup thinly sliced yellow onion
1 large bunch of Swiss chard, kale or spinach or any other leafy green vegetable of your choice
2 cloves of garlic, minced
8 oz sweet Italian sausage pushed out of their skins, or the sausage meat
1 cup drained, rinsed canellini beans
1 cup canned pumpkin puree, or even better, homemade roasted and mashed butternut squash
1 1/2 cups water or chicken broth
1/2 cup yellow cornmeal
a good pinch of freshly grated nutmeg
2 oz grated Pecorino Romano cheese
salt and pepper to taste

Heat a large saute pan over medium-low heat. Spray with nonstick cooking spray. Add the onions and cook, stirring occasionally, for about 10 minutes until softened.
Meanwhile, prepare the Swiss chard. Cut off the thick stems and slice the leaves into 1″ ribbons. Rinse in a colander and set aside.
Add the garlic and crumbled sausage meat to the onions. Season the mixture with salt and pepper. Cook till the sausage meat has turned from pink to light brown, add the white beans. Cook for another minute until the garlic is fragrant. Add the Swiss chard(or spinach etc) with the water still clinging to it. Stir to combine then cover the pan and raise the heat to medium high. Let the greens wilt down while you prepare the polenta. Stir occasionally.
Whisk together the water/chicken broth and pumpkin puree in a medium saucepan. Season generously with salt and add the nutmeg. Place the cornmeal in a small bowl and pour a little of the pumpkin mixture over it, stir well (this will make it easier to incorporate the cornmeal into the heated pumpkin mixture, without clumping)
Bring the remaining mixture in the saucepan to a boil. Whisk in the wet cornmeal until smooth, then reduce heat to medium high and cook, stirring often with a wooden spoon, for about 10 minutes.
When the polenta has thickened (if you draw the spoon across the bottom of the pan the line should remain visible for a short time) stir in the grated cheese and turn off the heat. Adjust with salt and pepper to taste.
Taste the sausage and bean mixture and season with salt and pepper if desired.
Divide the hot polenta between two plates and top with the sausage, white beans and chard.
