Bring a large pot of salted water to a boil and add the egg noodles. Cook until al dente, about 6 minutes.
12 ounces egg noodles
Add the olive oil, onion, garlic, and peppers to a large skillet and cook until fragrant and tender (about 5 minutes). Once cooked, remove veggies from the pan and set them aside.
1 tablespoon extra virgin olive oil, 1 cup bell pepper, 1 large onion, 2 cloves garlic
Oven medium-low heat, in the same pan, add butter and flour. Stir until butter is melted into the flour to form a paste. Slowly add the milk and stir to combine.
¼ cup butter, ¼ all-purpose flour, 2½ cups whole milk
Add in the cream cheese, and continue to whisk it into the mixture until it is melted, and no longer lumpy. The mixture will be thick and velvety.
8 ounces cream cheese
Once creamy, add in the noodles, drained tuna, peas, and precooked veggies. Season mixture with salt and pepper to taste.
12 ounces tuna, 10 ounces peas, salt & pepper
Transfer mixture into the greased casserole dish. Top with shredded cheese, and fried onion strings.
