Drain tomatoes, reserving 1/3 cup liquid. Stir tomatoes, reserved tomato liquid (discard remaining liquid) and fresh thyme into onion mixture. Cook and stir over medium heat about 2 minutes or until heated through. Stir in 3 cups of the spinach and stir about 30 seconds or until just wilted. Stir in remaining spinach and bacon. Spoon mixture into 4 individual bowls. Drizzle each serving with 1 teaspoon vinaigrette. Season to taste with salt and freshly ground black pepper. Makes 4 side-dish servings.
