My guests arrive in 6 hours. The shops are shut. I'm scared I haven't got enough. I've got a choice of 3 small starters, enough for 1 normal portion each of 8 veg mains, 16 meat mains, 3 salads of 10 normal portions each, 2 kilo berries and cream for dessert and 4 loaf cakes.BUt we are 13 adults, 3 kids, 3 toddlers. What if it's not enough? Is it terrible to fill gaps with frozen pizza?
