Mix the Sourdough starter with One and a half cups flour and two eggs. Add a little flour or water to get the correct consistency in the dough if it's not right. I used one cup all purpose and 1/2 cup dark rye flour. Whole Wheat would be good too but I did not have any on hand. Let the dough ferment a good long time. I usually mix it in the morning and let it ferment for about 3 hours and then punch it down. If it is a little wet, I add a little flour to make the yeast happy, nead it a bit and let it rise again for an hour or so.
Flour the surface and the dough real good and roll it out and cut it into noodles with a pizza cutter. Toss and let dry on the counter until it is time to prepare the dish. I cut them into 3 inch lengths this time. This is the first time I have used them in a casserole - we'll see.
Start a pot of noodle water to boil when you're ready to create dinner. I usually add a pinch of salt for good luck. A watched pot never boils, so leave it to it's business and get on with whipping up the secret sauce. Preheat the oven to 350°
The secret sauce. Campbell's soup just doesn't cut it folks. I understand convenience but there is just nothing in that can that is worth it. Make your own. I like to use a big cast iron dutch oven that I can cook it all up on the stove top and then put the whole thing in the oven. Saute the onions, garlic and celery in the oil for 5-8 minutes until tender and translucent.
Add the flour a little at a time stirring continuously until the flour begins to darken a bit and then add the broth a little at a time to maintain heat. Add the milk the same way.
Add the mushrooms and maintain heat to keep a nice burble going. Add the tuna. We are looking for a nice smooth, thick consistency. The chunky sourdough noodles are going to thicken it up though, so don't get it too thick. Add a little milk if you want it thinner or a little Arrow Root powder if you want it thicker. When it looks, oh so right, drop the temp to low and wait for the noodles.
When the noodle water comes to a boil, add the noodles a handful at a time to maintain heat. Once all the noodles are in, they will take about 5 minutes or so depending on how chunky they are. With about two minutes to go add the broccoli to the pot.
When the broccoli and noodles are done, pour off the water through a colander and stir them into the secret sauce in the dutch oven. Stir in the seasonings and adjust salt and pepper to taste.
Mix the almonds, cheese and bread crumbs together and sprinkle over the top.
Cover the dutch oven and cook covered for 25 minutes. Remove the cover and cook for another 25 minutes. Let it cool with the lid on for about 10 - 15 minutes and enjoy.
