Anything you can do to keep cool in the summer is a good thing.
I found a new (to me) sun tea jar at a thrift store, so I have been making decaffeinated sun tea. Just tap water and tea bags in my jar - along with the hot summer sun - are all I need to make it.
I don't want my iced tea to get diluted so I freeze some of the tea in our vintage aluminum ice cube tray that's been here in the house for nearly sixty years, put the cubes in the freezer in a plastic bag, and they are at the ready when I need them.
And when we just plain do not feel like anything hot for dinner, I will sometimes just fix us some nice big salads.
I made these salads not long ago - one for my husband with some leftover grilled steak that was in the fridge, red onion, goat cheese, tomatoes:
Keep cool, people, keep cool.
(If you possibly can - we are finding it rather difficult, here lately.....)
