Preheat your oven to 375 degrees Farenheit.
Remove the crusts from 8-10 slices of fresh white bread (or french bread) and tear apart. Place the torn pieces into a large plastic ziplock bag. Melt 6 Tbsp of Butter in a small saucepan and pour half of the melted butter over the bread. Seal the bag and toss the bread until well coated. Set aside.
In a large pot, bring 6 cups of water to a boil and add a pinch of salt.
While the water comes to a boil, take the remaining melted butter and brush with a pastry brush into a 3 Quart baking dish (or a disposable aluminium turkey roasting pan - for easy cleanup and transport). (Also, if you don't have a pastry brush, you can use a paper towel dipped in the butter to coat the pan). Set aside.
In another large pot on medium heat, melt 6 Tbsp butter and, once melted, add 1/2 cup all purpose flour. Whisk together to make a rue. Slowly pour in the warm milk and whisk constantly until all the milk is added and the sauce thickens and begins to bubble. Remove from heat.
Add the olive oil to the boiling water and stir in the pasta. Follow cooking instructions on the package for cook time or until the pasta is al-dente (firm, but not hard). Pour the pasta into a colander and rinse with cold running water and allow to drain.
Add 1/2 tsp Sea Salt, White Pepper, Nutmeg, Tarragon, Cayenne Pepper, Gruyere, Cheddar and Pecorino cheeses to the sauce mixture and stir until the cheese melts.
In a large bowl, combine the drained pasta and cheese sauce and pour into the buttered baking dish. Combine lobster, sea scallops and cooked bacon. Sprinkle the bread pieces over the top and place in the oven.
Bake for 30 minutes or until the top is golden brown and the cheese bubbles.
