I made a tray of Ooo-la-la-sagna from one of my favourite cookbooks, The Looneyspoons Collection. I left out the red pepper flakes since I used hot Italian sausage in this recipe. Oh and I threw in some chopped sweet yellow peppers and shallots. I also used gluten-free lasagna noodles (corn and quinoa) that I didn't have to pre-cook--easy!
Seriously, if you don't have this cookbook in your collection this is one that you should pick up and they have many gluten-free recipes in here too. The recipes that are not gluten-free are easily adaptable like the sweet potato crust on their Hungry Guy Chicken Pies recipe. I just substitute gluten-free flour for the regular flour they call for in the recipe and it worked out great.
I haven't found a recipe in this book that I don't love.
