Spinach shrinks considerably when cooked. It may look like a ton of leaves to begin with, but the volume will decrease drastically once it’s done.
You can use either baby spinach or mature spinach. I recommend trimming mature spinach stems before cooking.
Optionally garnish sauteed spinach with either lemon juice, parmesan cheese, or crumbled bacon. Spinach pairs well with proteins like chicken, pork, beef, and seafood. You can also toss your sauteed spinach into omelets or mix it into scrambled eggs for breakfast.
