Each food quantity = adult equivalents × the per-adult amount for the chosen menu; bread is rounded up to whole pieces.
Assumptions and limits
Per adult: 350 g raw meat for a mixed menu, 500 g for a meat-heavy menu and none for a vegetarian menu.
Per adult: 220 g vegetables (500 g for a vegetarian menu), 180 g side dishes and 1.5 bread rolls.
A child counts as 60% of an adult; light and hungry appetites use 0.8× and 1.25×.
No extra buffer is added. Add your own margin for seconds or uncertain guest numbers.
Worked example
10 adults and 4 children count as 10 + 0.6 × 4 = 12.4 adult equivalents. For a mixed menu that means 12.4 × 350 g = 4,340 g of raw meat, 2,728 g of vegetables, 2,232 g of side dishes and 19 bread rolls.

Reading the result
Meat amounts are raw weight before bones, trimming and cooking losses.
No safety buffer is included. If guest numbers are uncertain, add guests or choose “Hungry” rather than rounding every item up.
Cook meat until it is safe to eat; a thermometer is the reliable check for burgers, sausages and chicken.
