Preheat oven to 350ºF.
In a large bowl, combine eggs, sour cream, Italian seasoning, hot paprika, salt, and freshly ground black pepper; whisk until well blended. Add 2/3rds goat cheese, whisk and set aside.
In a 12-inch cast iron skillet over medium heat, add oil and when it gets hot, add pancetta. Cook until it starts to crisp, about 6 to 7 minutes; transfer to a plate lined with paper towels.
Return the skillet to the burner and add leeks; sauté for 2 minutes. Add peppers and a pinch of salt; cook for 3 minutes.
Add asparagus and cook just enough to remove their bitterness about 2 minutes.
Return the pancetta then add garlic; sauté for 1 minute.
Add the potato cubes and gently stir. Add a few splashes of hot sauce, stir and cook until the potatoes are heated through, about 2 minutes.
Turn off the heat and whisk the egg mixture before pouring it over the vegetable mixture; gently stir to blend. Add the remaining cheese on top and sprinkle with smoked paprika.
One to two minutes later when the outside edges start to thicken, transfer to the preheated oven. Cook until the eggs are puffy but the center jiggles a little, about 10 to 13 minutes.
Turn the broiler on and cook for 1 to 2 minutes. Remove from the heat to cool off, about 15 minutes.
