Yesterday, the Boston Globe had a recipe for roasted squash with za'atar, dill yogurt, and peanuts. Another summer squash recipe that looks interesting is Food52's raw squash salad with radishes, manchego, and lemon vinaigrette.
I've been brewing iced tea overnight a lot lately. We've been making cold brewed coffee for iced coffee as well. The natural progression would seem to be making breakfast by letting it sit overnight in the fridge. The Crepes of Wrath has a recipe for overnight cherry-almond oats.
