My step-daughter recently served us a salad from Costco which was delicious.
Since I already had kale and brussels sprouts I made my own version.
2 cups finely shredded kale
2 cups finely shredded Brussels sprouts
1/4 cup walnuts
1/4 cup chopped feta
Sliced apple with skin
Cucumbers - drained
I made my own salad dressing. Again, use whatever you would like.
There are so many other things you could add, so just use whatever you have lying around.
