Warm Sweet Potato Salad

3 Tbsp cider vinegar
3 Tbsp maple syrup (I used plain old pancake syrup)
3 tsp Dijon mustard
3 Tbsp olive oil
2 large sweet potatoes, peeled and cut into bite-size chucks
1 large onion, thinly sliced
8 oz ham, diced (I used deli ham, but I bet thick chunks would be even yummier)
3/4 tsp dried thyme
1/4 tsp salt
1/4 tsp pepper
1 package frozen chopped spinach, thawed and squeezed dry
1/2 cup chopped walnuts, toasted (I tried it with and without, and it's great either way
Heat oven to 400.
Stir together vinegar, syrup, and mustard. Whisk in 2 Tbsp oil and set aside.
Mix potatoes, onions, ham, 1 Tbsp oil, salt, pepper, and thyme and bake for 45 minutes.
Add spinach, walnuts, and vinegar mixture. YUM!
