For the sake of budget, I would say go with yellow curry. Use buns if you don't trust to stay alive within a 3 hour time frame. Great attack food with a huge STR bonus and AGI on the side. This is of course assuming you won't be compromising too much accuracy as to have half your slugwinders miss.
On a side note, I much rather rearrange my gear that allows me to make full use of meat food with decent accuracy rating than ever resorting to sushi.
