Melt the butter in a small skillet over medium heat. Toss in the pecans and brown sugar, stirring to coat. Cook over medium heat until the sugar begins to caramelize (about 3 minutes). Spread out pecans on a wax paper lined baking sheet to cool.
In your salad bowl layer the spinach leaves, strawberries, goat cheese and pecans. Don't pour dressing on salad until ready to serve. Enjoy!
