Jazzed Up Tuna Melt. I’d like nominate Sundays as the best day of the week.A good Sunday should be drenched in a late sleep, strong coffee, brunching, watching favorite TV shows (specifically Breaking Bad), judging celebrities and especially, this tuna melt.Can I share my favorites from last night? I loved: Cate Blanchett, Mila Kunis, Mandy Moore (hello! Where has she been?). Your turn…! I’d also like to nominate the tuna melt as the best sandwich. Ever.I first had a tuna melt with carmelized onions at this little cafe I’ve frequented, and it’s stayed with me. Print this recipe! Tagged as: Cheese, Potato Chips, Tuna Salad.
