Classic Turkey Tetrazzini Recipe

I love the month of November, and comfort recipes like Turkey Tetrazzini! If you have any leftovers from this Apple Cider-Brined Turkey, then save them for this recipe!

Here’s the beauty of this easy dish. Yes, it’s a dish that is great with leftover Thanksgiving turkey, but it’s also a great meal for doubling up the recipe, and bringing to a friend or two who might need a meal. Right? I did this recently. It’s a great hospitality dish.

Here’s another classic dish you may want to try: Tuna Noodle Casserole.

I bought a lot of these ingredients at Trader Joe’s, like the mirepoix. Do you ever use it for a quick soup or recipe?

What is mirepoix?

Mirepoix is a combination of chopped carrots, celery and onions! We buy it all the time at Trader Joe’s, for quick and easy recipes like Slow Cooker Mirepoix Roast Beef and Chicken Curry Crock Pot Lentil Soup.

Smith Rock, Oregon

You may not know me well, but I do tend to look for the little gifts in life each day. Whether it be a sunrise, sunset, a cup of coffee, or dinner with friends—magic can be found in the everyday life.

A week ago today, I stopped work and went out to enjoy life a little. We went on a 5-mile hike on an unusually warm November day, and we’re so glad we did.

Crooked River, OR

We have to remember our to-do lists are not going anywhere, and especially during these days, it doesn’t do any good to do the anxious scroll. You know what I mean. We have to purposely turn off the news, and go do something unusual. Really, the purpose of our lives is not productivity, even though lately I feel mine is. Yes, I’m working on a project I can’t wait to share with you soon!

So a hike with our dog, Alder, and then home to leftover Turkey Tetrazzini—the perfect kind of warm fall day.
