Exercise Food Ideas?

[Guest guest]

When I play tennis, I'm typically on the courts pretty much the whole

day. It's time-consuming to get there, tennis is fun, getting fresh

air is good, I want the most exercise bang for my time buck, etc. etc.

etc. So needless to say, I need to bring food with me.

This is where it gets complicated, though, so I could use some

suggestions. I've tried jerky, but it's too lean -- I stay hungry

after eating it. (And to date, I haven't found or made any pemmican

that I can bear to gag down.) I've defaulted to bringing salami to

the court, which keeps well (because it's cured) and satisfies

(because it's very fatty) but of course there's the pig fat PUFA

factor along with other drawbacks, so I really want to stop doing

that. I've sometimes brought kefir or yoghurt smoothies in a

thermos... but that's often my breakfast, and I don't want to have two

of those in a day. Besides, the sugar:fat ratio is really too high

for enduring satiation, and the protein content might also be too low

to keep me full for any real length of time, so at best that's an

adjunct, a snack, rather than a full meal.

I do have a second thermos meant for food rather than drinks, but

needless to say, the idea of bringing any kind of hot food out on a

hot summer day is utterly beyond contemplation, so it'd have to be

used for something cold but also fatty and fairly proteinaceous.

Any suggestions?

TIA,
