Pizza #1: tomato sauce, fresh mozzarella (from B.W.), and basil (from our backyard).
Pizza #2: sauteed swiss chard and onion, fresh mozzarella

Preheat a gas grill or broiler (grill). Position the cooking rack 4 to 6 inches from the heat source.
Arrange the chilies skin-side down on the grill rack, or skin-side up on a broiler pan lined with aluminum foil. Grill or broil until the skins begin to blacken, 5 to 7 minutes. Transfer to a bowl, cover with plastic wrap and let steam until the skins loosen, about 10 minutes. Peel the chilies, discarding the blackened skin, and chop coarsely. Set aside.
Put the potatoes in a saucepan, add water to cover, and bring to a boil over high heat. Reduce the heat to medium and cook, uncovered, until the potatoes are tender, 15 to 20 minutes. Drain and transfer to a small bowl. With a potato masher, partially mash the potatoes and set aside.
In a large saucepan, heat the olive oil over medium heat. Add the onion, celery and bell pepper and saute until the vegetables are softened, about 5 minutes. Stir in 1/4 teaspoon of the salt and cook for 3 to 4 minutes longer. Stir in the roasted chilies and the partially mashed potatoes. Add the corn, vegetable stock, milk, pepper and the remaining 1/4 teaspoon salt. Simmer uncovered until the soup thickens, 25 to 30 minutes.
Ladle into warmed bowls and sprinkle with the cilantro and oregano. Serve immediately.
