Heat the oil in a heavy large frying pan over medium heat. Add the onions and saute until tender, about 8 minutes. Add the chard and saute until it wilts, about 2 minutes. Add the garlic and saute until fragrant, about 1 minute. Stir in the tomatoes with their juices, wine, and red pepper flakes. Bring to a simmer. Cover and simmer until the tomatoes begin to break down and the chard is very tender, stirring occasionally, about 5 minutes. Season the chard mixture, to taste, with salt and pepper.

Meanwhile, bring a large pot of salted water to a boil. Add the spaghetti and cook until tender but still firm to the bite, stirring frequently, about 8 to 10 minutes. Drain the spaghetti. Add the spaghetti to the chard mixture and toss to combine.

Transfer the pasta to serving bowls. Sprinkle the olives, cheese, and pine nuts and serve.

Preheat the broiler. Whisk the eggs, cream, 1/2 teaspoon salt, and pepper in a medium bowl to blend. Set aside. Heat the oil and butter in a 9 1/2-inch-diameter nonstick ovenproof skillet over medium heat. Add the asparagus and saute until crisp-tender, about 2 minutes. Raise the heat to medium-high. Add the tomato and a pinch of salt and saute 2 minutes longer. Pour the egg mixture over the asparagus mixture and cook for a few minutes until the eggs start to set. Sprinkle with cheese. Reduce heat to medium-low and cook until the frittata is almost set but the top is still runny, about 2 minutes. Place the skillet under the broiler. Broil until the top is set and golden brown on top, about 5 minutes. Let the frittata stand 2 minutes. Using a rubber spatula, loosen the frittata from skillet and slide the frittata onto a plate.
