A three-compartment, disposable food serving plate includes three ribs in an asymmetric array angularly joined to the bottom and sidewall of the plate. The plate preferably includes a four radius, smooth profile from the bottom to the outer rim and is formed from mineral-filled polyolefin sheet. Mica-filled polypropylene is particularly preferred.
