🍚 盛 = 成 (become, grow) + 皿 (dish): a dish that grows into a heaped serving
The 皿 dish radical at the bottom marks food piled on a plate, as in 大盛り, a large serving. Note: read もり (mori), it means a serving. Read さかり (sakari), it means peak or prime, the height of a season.
盛 — 成 (chéng, phonetic) + 皿 (vessel)
A phono-semantic compound: 皿 (a dish or vessel) gives the meaning, while 成 supplies the sound. The original sense was grain heaped into a ritual vessel as an offering, hence 'to fill' or 'contain' (chéng). From 'full to the brim' it extended to 'abundant, flourishing, prosperous' (shèng).
