Planning basics

How much food do I need?

This is the question we get most, so here's the short version for meat trays:

Full tray

Feeds about 35–40 people, served alongside rice, beans, and tortillas.

Half tray

Feeds about 17–20 people. Good for smaller gatherings or as a second meat option.

Not sure?

Tell us your headcount when you call or submit an order, and we'll help you land on the right mix of trays and sides.

Sides, salsas, and extras (rice, beans, guacamole, tortillas, chips, limes) are sold by the gallon, half-gallon, box, or pound rather than by headcount — our team can help you size those once we know your meat order.
