Preheat the oven to 425ºF.
Roll puff pastry on floured surface into a circle approximately 13 inches wide. Press dough into an 11-inch tart pan. Place a piece of foil sprayed with nonstick cooking spray over the dough and fill with dried beans or pie beads. Bake 8-10 minutes or until golden.
Meanwhile, cook sausage in a large skillet over moderately high heat, breaking it up as it cooks, until the sausage is no longer pink, about 7 minutes. Drain well. Transfer sausage to large bowl and add the tomatoes, garlic, basil, pepper, salt and cheese.
In separate bowl, whisk the eggs, cream and milk together. Combine both mixtures; mix well.
Pour into the baked shell and bake an additional 15 minutes. Reduce oven temperature to 350ºF. Bake an additional 10-12 minutes or until egg mixture is set and golden. Remove from oven; cool 5-10 minutes before cutting.
