Summer make-ahead food

So I’ve discovered a new favorite summer breakfast!  I found it in The Family Cooks, which is the latest adorably packaged, make-your-family-eat-better idea book.  It’s “Fresh, Fruity Summer Porridge” – basically a kind of muesli – and there’s nothing to it.  You just grate an apple in some yogurt, add some oats and layer in some fruit and something sweet (honey, say), then throw the whole thing in the fridge.  Voilà, instant porridge in the morning – cool and sweet and no fussing with the stove.  The only thing is remembering to do it the night before.

It’s funny, I think of make-ahead meals as a winter thing – think slow cookers, burbling away while everyone’s at school or the office (or plodding away at their home treadmill desk).  But summertime’s a make-ahead time too.  Mostly because you maybe don’t want to heat up the house.  Or maybe because you can’t be bothered with cooking cooking after you’ve dashed in your house and peeled off your swimsuit in the late afternoon.

Hence the appeal of cool soups, and homemade sodas, and marinades (which were among my spring resolutions, and are fast becoming a hot-weather  standby for me) – all of which have some labor up front, granted.  But by the time you settle down to eat, that’s all forgotten.

What are your summer make-aheads (and can I borrow them)?
