- 2 cups chicken broth (3.5 cups for Instant Pot instructions)
- 1 cup onion, diced
- 8 oz canned mushrooms, sliced and drained
- 2 tbsp Italian seasoning
- 3 cans tuna (5 oz each), drained
- 1 ½ cups frozen peas
- ½ tsp salt
- ½ tsp pepper
- 1 cup shredded cheddar cheese

Instructions
- Cook the egg noodles until slightly underdone according to package instructions. Drain well and set aside.
