Canned tuna is a life-saver when fridge and freezer are empty. Try to choose high-quality, MSC-labeled tunafish—preferably in olive oil instead of sunflower oil.

Yes, you can freeze this dish.
You may wish to omit the celery, there is not a great substitute.
I used my cast iron skillet so sautéed the vegetables and then added the rest and popped in oven. One pan clean up made it that much better.
This dish makes four servings as written. All of the nutrition information is in the Nutrition+ tab under the list of ingredients.
That depends on how much your dish reduces as it cooks. The recipe as written makes 4 servings, so a serving is 1/4 of the finished dish.
Would probably even do 3/4 cups of mayo instead of 1 cup the next time.
Wonderful! I am so glad you enjoyed these!
Light mayo is usually lower in fat and higher in sugar/carbs, which is the opposite of what you want to consume. It's super easy to make your own mayo, though. Check out our recipe! https://www.dietdoctor.com/recipes/mayonnaise
This will sound like a silly question, and I can certainly improvise without an answer but...how are you suggesting the spinach specifically be served? Simply on the side, cold without dressing, just tossed in oil? Or is the casserole meant to be served on top of a bed of spinach? Just seems as an inconsequential addition, especially without a little more detail...not to mention a photo that reflects exactly as the recipe seems to suggest. Or just leave out altogether.
I do like the idea a respondent recommended by baking the spinach inside the casserole. That sounds wonderful.
Or...picking up on what one of the "if you liked this recipe, you may like these" photos that shows a side of baby spinach leaves with egg and tomato slices that would finish off the recipe completely all the way to the presentation stage.
Hi JC, in any of our recipes, if we don't make a specific suggestion like for the spinach in this case, it is because we want to leave it up to you, to serve it however you prefer as it doesn't make a difference for the nutrition information. Some people prefer a little spinach salad on the side while others may prefer the texture of serving the casserole on a bed of spinach.
Sounds great! Thanks for the feedback!
