Position a rack in the upper third of the oven and preheat to 400 degrees F. Whisk the gravy and 1 tablespoon flour in a medium ovenproof skillet; bring to a simmer over medium heat, whisking frequently. Add the brisket, sauerbraten vegetables, squash, thyme, 1/2 teaspoon salt, and pepper to taste. Cook, stirring gently, until the squash is heated through, about 5 minutes. Spread the mixture in an even layer in the skillet.
Whisk the corn, eggs, cheese, the remaining 1 tablespoon flour, and pepper to taste in a bowl. Pour over the meat mixture, transfer the skillet to the oven and bake until the topping is set and browned in spots, 30 to 35 minutes. Let rest a few minutes before serving.

Sprinkle the brisket with 1 teaspoon salt and 1/2 teaspoon pepper and cut crosswise into 3 pieces. Heat the olive oil in a large skillet over medium-high heat, add the brisket in batches and brown, about 3 minutes per side. Transfer to a 5- to -6-quart slow cooker.
Add the tomato paste to the skillet and cook, stirring, 1 minute. Whisk in the wine, vinegar and pickling spice sachet and simmer 4 minutes. Add to the slow cooker along with the beef broth, carrots, celery, leeks and half of the gingersnaps. Cover and cook on low, 8 hours.
Remove the meat, vegetables and spice sachet. Whisk the remaining gingersnaps into the cooking liquid and add salt, pepper and parsley to taste. Set aside 1 piece of brisket, 1 cup vegetables and 2 cups gravy for another use. Slice the remaining meat and serve with the vegetables and gravy.
