Tuna and Asparagus Casserole Recipe

This week I decided to try something new – I am not an olive lover but my entire family is so I thought this would be a winner. The flavors just sort of melt together so well without needing a lot of spices so this is one of those favorite healthy recipes – the kids loved this asparagus casserole recipe with tuna and olives!

Asparagus Casserole Recipe

While I was growing up my parents were too busy to have a garden of any kind, but we did inherit a little asparagus patch in our backyard from the previous owners of our house. Those owners had the last name Jackson and I was convinced as a 7 year old that Michael Jackson had lived in our old farmhouse in New Hampshire.

One thing I really loved about that house besides the old built-in cabinets and corn crib where we installed a swing was being able to go out back and pick asparagus for dinner. I was amazed that we could eat something straight from the earth.

My kids don’t love asparagus, but they will eat this asparagus casserole. I like to cut the asparagus into tiny pieces so it’s harder for them to pick it out!

Asparagus is packed with antioxidants and can help fight cancer. Asparagus also is a great diuretic as it contains high levels of the amino acid asparagine. Did you know asparagus is one food that you don’t have to buy organic?
