Bring a large pot of water to boil and cook the egg noodles according to package directions until al dente. Drain and transfer the pasta to a bowl. Set aside.
In the same pot, reduce the heat to medium and add the avocado oil.
Saute the onions for 3-5 minutes until it begins to soften and become translucent. Then add the minced garlic and saute for another 1 minute, until fragrant.
Sprinkle on the all purpose flour and seasonings then stir together. Continue to stir and cook for 2–3 minutes.
Slowly pour in the chicken broth and stir continuously until well incorporated and there are no clumps of flour.
Stir in the half and half and reduce the heat to a low simmer. Continue to cook and stir often until the sauce begins to thicken into a gravy-like consistency, about 5-7 minutes.
Add in the cooked noodles, thawed veggies, and tuna. Mix to combine and let cook for 5 minutes.
Remove from the heat and stir in the freshly grated cheese.
Garnish with fresh chopped parsley if desired. Serve and enjoy!
