Preheat oven to 400°F. Line rimmed baking sheet with foil. Place tomatoes in center of sheet. Add 1 tablespoon olive oil, Sazonador Total, and 2 teaspoons thyme; toss until evenly coated. Arrange, cut sides up, in single layer. Bake until reduced slightly and edges are browned, about 1 hour. Chill and coarsely chop.
Brush thawed Discos with 2 teaspoons olive oil. Sprinkle on ½ cup manchego cheese and remaining 2 teaspoons thyme. Bake until pastry is golden, about 14 minutes.
Top with tomatoes (about 2 tbsp. each) and remaining cheese. Bake 5 minutes or until cheese is melted. Drizzle with remaining 2 teaspoons olive oil and top with slivered basil.
• You may substitute frozen puff pastry for GOYA® Discos. Cut dough into 6" pieces.
• The tomatoes can be roasted and stored refrigerated, for up to 1 week in advance. Bring to room temperature before using.
