1½ small onions; divided use
2 large carrots; chopped fine
3 sticks celery; strings removed, chopped fine
2 12-oz-cans tuna
1 qt milk 12 oz mushrooms;
sliced 8-9 oz egg noodles; or your choice of pasta
½ cup panko or crushed potato chips
salt,
pepper,
flour,
butter

Slice the mushrooms and mince half of the onion. Start the onion in some butter and get it almost to the point of carmelization then dump in the mushrooms. Sauté over medium-high heat until substantially reduced in volume. (I did this a day or so before doing the final recipe so haven’t tried to incorporate it into the timeline.) Dice the whole onion and prepare the carrots and celery. Warm the milk or let it come to room temperature. Steam the carrots and celery and, meanwhile, sauté the onion in lots of butter or olive oil. When the onion is translucent, add about 1/3 cup of flour and stir it for a while. Add the milk and bring to a boil then cut it back to med low heat. Add the mushroom mixture and stir. Taste for salt and pepper. If it doesn’t thicken enough, mix some olive oil and flour and add enough to get it thickened properly. Add the carrots and celery. Have the noodles about halfway cooked and add them and the tuna and mix thoroughly. Pour into a 9×13 pan and cover with the panko or chips. Put into a 375ºF (190ºC) oven for about twenty minutes.
