A mobile-dining mealholder with a plate-lid and detachable bottle, the bottle including a narrow cylindrical neck with projections at axially-spaced positions, and the plate-lid including (a) a horizontal cap portion having a downwardly-extending cylindrical skirt with projections at axially-spaced positions such that the skirt detachably engages the neck and (b) a tray portion extending outwardly from the lower edge of the skirt and having food-holding areas about the cap portion. Certain preferred embodiments involve: the tray portion having depressed regions and vertically-extending portions positioned transverse to imaginary pivot lines across the tray portion to avoid excessive flexing; the tray portion being complementary to a shoulder portion of the bottle for enhanced support; and/or either push-on or quarter-turn engagement of bottle and plate-lid.
