Tuna casserole is a dish made with noodles, canned tuna, and other ingredients mixed together and baked in an oven. Think of it like mixing together different things that you like to eat, like macaroni and cheese or spaghetti, and adding tuna to it.
To make tuna casserole, you first cook some noodles in boiling water. Noodles are long and skinny like worms, but they are made from different things like wheat or rice instead of animals. You have to make sure to cook them just right so that they aren't too hard or too soft.
Next, you mix in some canned tuna which is fish that comes in a can. Tuna fish is full of protein which helps you grow strong and healthy.
You can also add in other things that you like such as frozen peas, corn, or even cheese. Cheese is a yummy food that is made from milk and tastes really good in tuna casserole.
Once everything is mixed together, you put it in a dish and bake it in the oven for a little while. The oven is like a big hot box that uses heat to cook your food. When it comes out of the oven, it is hot and bubbly and ready to eat.
So, there you have it! Tuna casserole is a yummy and easy-to-make dish that you can enjoy with your family and friends.
