Is it no longer possible to order vegetarian meals for domestic (NYC-MIA) F and caribbean (out of MIA) J class flights?

Either way, what should we expect as a breakfast in F NYC-MIA? Is it just an inedible muffin and a o/j , or more than that? Should we choose seats bck (odd numbered flight) for a choice?

And for the J lunch service to UVF from MIA, what should we expect (no veggie meals? any choice?) Or should we pack our food, Ryanair style?
