I chose this recipe as one of my PAC babies as it had no reviews and I love being the first to review. Besides it sounded just enough different from the usual tuna casseroles that we enjoy that I really wanted to try it. Glad I did, it was good, though I think I may still prefer noodles as I'm not a big soaked bread person- but the flavors all came through nicely and DH really enjoyed it, will be having left overs tonight. Made for Spring PAC 2013
