To prepare, soften tortilla by warming briefly in skillet or microwave. Brush both sides of tortilla lightly with vegetable oil and gently push into 1-cup custard dish or small oven-proof bowl. Line with foil and weight with dried beans or rice. Bake, uncovered, at 400 degrees F for 7 minutes. Carefully remove shell from bowl and allow to cool. Adjust bowl and tortilla size for larger baskets.
