This step is optional, but if you want to toast the pecans simply spread them out on a baking sheet and toast in a 350° F oven for about 6-8 minutes. Remove from the oven and let cool.
Make creamy balsamic vinaigrette dressing if you haven't already.
Add spinach to a salad bowl and top with strawberries, avocado, goat cheese and pecans. Sprinkle on salt and pepper, to taste.
Drizzle dressing over salad and toss or portion the salad and pass around the dressing to serve.
Notes
Red onion: Feel free to add 1/4 cup sliced red onion to this salad for extra flavor.
