Equipment

Instant Pot 6 qt
Stock Pot
Kitchen Knife

Ingredients

12 oz whole grain egg noodles
5 large mushrooms sliced
1 cup frozen mixed vegetables diced carrots and peas
1 ½ cups cream of mushroom soup homemade or canned low sodium (2 small cans)
2 cans chunk white tuna in water with no salt added, broken up with a fork (I like Wild Planet brand)

Instructions

Oven Instructions:

Boil noodles (about 3C dry, maybe a little over) until tender (according to package directions), strain. 12 oz whole grain egg noodles
Stir in vegetables, homemade soup, and tuna. 1 cup frozen mixed vegetables, 5 large mushrooms, 1 1/2 cups cream of mushroom soup, 2 cans chunk white tuna in water
Allow the "casserole" to cook on medium heat until heated through, about 15 minutes. Add almond milk if you notice it drying out at all.
If yo'ud like to bake this instead of allowing it to heat on the stove, add the recipe to a baking dish and cover with foil. Baje for 25 minutes at 350º.

Instant Pot Instructions:

Spray the bottom of the pot with olive oil to avoid food sticking.
Drain and break up each can of tuna and put it on the bottom of the pot. 2 cans chunk white tuna in water
On top of the tuna, add the mushrooms if you're including them. 5 large mushrooms
Add 4 cups of pasta on top of the mushrooms and tuna, but don't stir. Add the cream of mushroom soup on top. 12 oz whole grain egg noodles, 1 1/2 cups cream of mushroom soup
You can add the frozen vegetables at the top if you'd like, or if you like them a little crunchy, cook them in the microwave and add them after the tuna casserole is cooked. 1 cup frozen mixed vegetables
Add 3 cups of water on top of the pasta and close the lid. Set the Valve to Sealing and cook on high pressure for 4 minutes.
As soon as the pot is done cooking, release the pressure manually. This means switch the valve to Venting and allow the steam to shoot out.
Remove the lid and stir the recipe. Add the cooked vegetables now if they're not in the pot already and stir again.
Allow to cool for a few minutes and serve!

Notes

Healthy Eating Plans

This is a healthy recipe for weight loss because it's packed with protein and whole grains to keep you full for longer.

Weight Watchers:

To keep points lower, we usually eat this as a side dish. Points are calculated based off of 1/2 cup serving with a total of 8 servings. If you eat this as a meal, 1 cup serving would be double the listed points.

3 2025 Plan Points | 3 Blue Plan Points | 3 Green Plan Points | 1 Purple Plan Point | 7 Points on the 2023 Plan when using homemade Cream of Mushroom soup.

Portion Fix/21 Day Fix:

On the Fix, this is a side dish–this recipe makes 8 servings, about 1/2 cup each. Remove the carrots and peas and double the mushrooms. For the entire recipe, the count and breakdown is:

Noodles: 8 yellow containers
Homemade Soup: 1.5 tsp and 1/3 green containers (canned soup isn't something that I'd eat on the Fix)
Mushrooms: 1 green container
Tuna: 2 red containers

For one serving: I'd count 1 yellow, 1/4 red container, and a negligible amount of a teaspoon and green container (I wouldn't count those).

2B Mindset:

Double the veggies and you've got a great 2B Mindset lunch. I'd personally double the tuna as well to get some more protein into my day. You could add diced onions if you like them and are looking for an easy way to bulk up the vegetables.

This is an easy recipe to meal prep. If you are on 2B Mindset and need lunch recipes, definitely make a batch of this for the week. You'll be impressed by how well it holds up in the refrigerator throughout the week, having something healthy on hand will make meal times a breeze too!
