Re-using tin boxes

The lovely clear skies of the past three days were gone today. The weather was grey and snow was trickling out of the sky. So, a change of course, time for an indoor day of baking.
Today I filled these two boxes with crisp bread (crackers?) made from seeds and rye sourough discard. Now we have enough to last us a fair while, and it's definitely healthier than the shortbread that came in these tins. Which is best? I can't answer that question because one is sweet and one is savoury, so it would be like comparing apples with yoghurt!
As I write this I am eating the crunchy edge pieces that get singed. They are so moreish just as they are. I must stop eating them!! Okay, just another two pieces...
