• Preheat the oven to 425° F.

For the Filling:

• Heat the olive oil in a deep sided sauté pan over medium heat. Add the onions and the garlic, and cook, stirring frequently, until the onions soften (about 5 minutes).
• Add the ground beef and turkey, and break it down with a fork, and brown the meat, stirring frequently.
• Stir in balsamic vinegar, salt, and worcestershire sauce, followed by the carrot, celery, and corn. Cook for about 5 minutes.
• Add the canned diced tomato, beef broth, bay leaf, thyme, and flour. Bring to a boil then lower heat to a simmer. Season to taste with salt and pepper, as well as Tabasco.
• Cover the pan and let it simmer for about 10-15 minutes.

For the Biscuits:

• Meanwhile, make the biscuits. In a large bowl, stir together the Bisquick mix, butter, buttermilk, cheese and thyme leaves.
• If making individual servings, divide the dough into 4-6 pieces, and gently form them into disks.

Combining the Dish:

• Divide the filling into individual ramekins or oven safe dishes. Top with biscuits and place on a baking tray. Alternatively, this can be made in one large dish, if you prefer.
• Transfer to the oven and bake for about 15 minutes, until the biscuits are lofty and golden. Serve immediately.
