Roughly chop spinach with just a pass or two of a chef's knife to get the leaves down to bite-sized pieces.

Heat butter in a large skillet over medium heat. Add spinach and garlic.

Cover skillet and stir every minute until all (most) of the leaves have wilted.

Uncover, increase heat and stir constantly for 1-2 minutes.

Remove from heat drizzle lemon juice on top and serve.
