Prepare the Salad Ingredients

1. Wash and Dry the Spinach: Start by washing the spinach leaves thoroughly. Use a salad spinner to dry them, ensuring they’re not too wet when you combine them with the dressing.
2. Slice the Strawberries: Hull the strawberries and slice them into thin pieces. The more uniform your slices, the prettier the salad will look.
3. Prepare the Red Onion: If you like a little extra sharpness, thinly slice the red onion and add it to the salad. If you’re not a fan of raw onion, feel free to skip it.
4. Chop the Walnuts: Chop the walnuts into smaller pieces for a better crunch and easier eating.
5. Crumbled Cheese: Crumble the feta cheese (or goat cheese) over the salad to add that creamy, tangy flavor.

Make the Dressing

1. Whisk the Dressing: In a small bowl, whisk together the balsamic vinegar, olive oil, honey, salt, pepper, and Dijon mustard (if using). Taste and adjust the seasoning as needed. You want a good balance between tangy, sweet, and savory.
2. Pour Over the Salad: Drizzle the dressing over the prepared salad just before serving. Toss everything gently to coat the spinach and strawberries with the dressing.
