Prepare the Spinach – Rinse the spinach under cool water. Dry the leaves in a salad spinner.
Make the Dressing – In a medium bowl, whisk together balsamic vinegar, honey, poppy seeds (if using), Dijon mustard, mayonnaise (if using), salt, and pepper. Slowly drizzle in the olive oil and whisk until it becomes a lightly thickened emulsified dressing. Season to taste.
Dress the Spinach – Add the spinach to a large serving bowl. Drizzle on ¼ cup of the dressing, and toss to coat.
Assemble the Salad – Top the spinach with strawberries, onions, pecans, and goat cheese.
To Serve – Serve the spinach salad with extra dressing on the side. Garnish with poppy seeds if desired.
