Place raw chicken in a 3 Qt saucepan with water to cover
Cover pan and poach chicken on medium low heat for 60-90 minutes
Remove chicken and drain, reserving broth for cooking pasta, and chop or shred chicken
Blue Ribbon Chicken Gratin
Bring a large pot of water, seasoned with 1 tsp of salt to a boil or use reserved chicken broth
Add spaghetti and cooked al dente {until just barely done} and drain
Cook bacon in skillet until crisp, remove to paper towels to drain
Saute onion and peppers in bacon fat until softened, about 5 minutes
Add ham to skillet and stir fry 2-3 minutes.
Add spinach to skillet and cover pan
After several minutes, remove cover and stir spinach down into vegetable mixture as it wilts
Add Velveeta, soup and cream, cooking and stirring for several minutes to incorporate and melt cheese
Season with salt and pepper and add chicken to sauce mixture in skillet and add 1/2 of the pasta
Stir well to combine, then add remaining pasta in increments, making sure the ratio of pasta to sauce remains very creamy. The casserole should be dense and very "wet."
Turn mixture into a greased 8" x 8" deep baking dish and top with Cheddar and Parmesan
Can be covered and refrigerated at this point for up to 36 hours before baking
Bake at 350 degrees for 45-60 minutes until hot and bubbling
