Great question — answering as the UphillTech team:
ExpertFlyer has meal information in its "flight details" search. For example, searching for your flight reveals that meal "D" is included, and clicking on the "D" shows that it means "dinner". Note, however, that this is a paid service (plans start, as of this writing, at $4.99/mo), though there is a free trial available if you just have a one-time need for this information.
