Spinach, apples, red onion, feta cheese, and sunflower kernels all dressed in a sweet Italian dressing
Place all of the dressing ingredients in a jar with a lid and shake until well combined.
In a large bowl add salad ingredients.
Toss well with half of the dressing and taste to see if it is well dressed. If you need more, add a little at a time until salad is lightly coated but not drenched.
