Slow cooker bacon and cheese scrolls. I put these on at lunchtime and they are warm and ready for the teens when they get home from school. Also try leftover cooked chicken shredded, with tiny bits of pineapple, grated cheese and a sprinkle of tarragon.
Tutorial for easy DIY knot headbands. Cute, simple look. There's also a quick tutorial near the bottom of the post about making one of these out of a non-stretchy fabric, sewing part of headband to be more elastic-like.
