In this tutorial, we learn how to make a simple tuna casserole. You will need: egg noodles, cheese, peas, onions, cream of mushroom soup, tuna, and sun dried tomatoes to make this recipe. First, pour your egg noodles into a mixing bowl, then cut up your onion. After this, pour a half bag of frozen peas into the bowl with the pasta and mix together. Now, shred your cheese and add it in with the pasta, then add in the onion and your tuna. Finally, add in the cream of mushroom soup and mix everything together until well combined. Chop your sun dried tomatoes, then mix those in as well. When finished mixing, pour your casserole into a dish and place it into the oven with the top on. Let this cook until the noodles are tender, then serve when hot and enjoy!
