Swiss Chard and Artichoke Pizza

Pizza dough (or puff pastry, if you defrost that instead by mistake - hee hee)
6 to 8 ounces mozzarella, thinly sliced or shredded
3 tablespoons olive oil
1 cup finely chopped onion
4 cloves garlic (or roasted garlic), minced
1 bunch Swiss chard (about 12 ounces or 4 packed cups of leaves), leaves and stalks separated and both chopped into small pieces
1 14-ounce can artichoke hearts (packed in water), drained and rinsed, chopped into small pieces
3/4 cup freshly grated Parmesan cheese

Heat oven to 500 degrees.

Heat olive oil in a 4-quart or larger pot.  Add onion and chopped Swiss chard stalks.  Cook over medium heat, stirring frequently, until soft, about 6 to 8 minutes.

Add garlic and cook, stirring frequently, about 2 minutes; do not let the garlic brown.

Stir Swiss chard leaves and chopped artichoke hearts into onion mixture.  Cover and cook, stirring occasionally, about 10 to 12 minutes.

Remove pan from heat and let chard mixture cool slightly.  Stir in Parmesan. 

Shape the dough on a baking sheet/pizza pan.  Spread the chard mixture evenly over the dough, then top with mozzarella.

Bake for 12 to 15 minutes, or until the crust is golden and the cheese is starting to brown.  Slice and serve.
