1. Pre-preparation of Ingredients – Chop, chop, and prepare ingredients in advance to save time during cooking.
2. Batch Cooking – Prepare food in large quantities and store it in portions to serve easily when guests arrive.
3. Set Up Buffet Style – Instead of serving food individually, set up a buffet where guests can serve themselves, reducing the need for serving each person.
