muffaletta sandwich

I've come across the amazing Muffaletta Sandwich and was wondering if it's possible to create a brittish/bento/gluten free version!

It just looks amazing!

Just looking at this now is making me really really hungry! Its just my kind of thing, Salami, cheese, olives, salad ect - awesome!

Today my bento is a little dull in comparison:

Salad, tomatoes, cottage cheese and cucumber! Bring on tomorrows Muffaletta!
