When you're planning a party, food and drink will require the most planning and preparation. When you plan to serve a meal for 60, your best bet is to figure in a little extra food to make sure you do not run out of food. For example, calculate the right amount of pasta salad and coleslaw to serve 70 people instead of 60 to ensure there is enough food for all your guests.
Use the number 70 instead of 60 when calculating food amounts to give you a cushion for extra servings and leftovers. Guests may over-serve themselves at a buffet. Using the higher number will prevent food shortages.
Multiply 5 oz. by 70 to determine how much pasta salad you need. According to the Great Party Recipes website, you should figure 4 or 5 oz. of pasta salad per person. Multiplying 70 by 5 equals 350. Divide 350 oz. by 16 to get 21.875 lbs. of pasta salad. Round this up to 22 lbs. if you desire.
Multiply 4 oz. by 70 to determine how much coleslaw you need. According to the Great Party Recipes website, you should figure 3 or 4 oz. of coleslaw per person. Multiplying 70 by 4 equals 280. Divide 280 oz. by 16 to get 17.5 lbs. of coleslaw.
