Warm Spinach & Sweet Potato Salad (with BACON!)

I went to a cooking class at a new grocery store in my neighborhood, Natural grocers, a couple weeks ago and they made this recipe. It's paleo. It's healthy. It has bacon!! It's delicious!

Salad:
3 cups peeled & diced sweet potatos
1tbsp coconut oil
8 strips of bacon, diced
2 leeks, thinly sliced
6 oz fresh baby spinach (the store was out so I used baby romaine instead)

Dressing:
1/4 cup olive oil (can use half bacon grease)
1 tbsp apple cider vinegar
1 tsp spicy brown mustard
Fresh ground black pepper to taste
1tbsp dried basil

Preheat oven to 400. Toss the diced sweet potatoes with coconut oil and spread evenly on s baking sheet. Bake in preheated oven for 20 minutes.
While the sweet potato is baking, cook the diced bacon in a large skillet. Once the bacon is crispy, add the sliced leeks & sauté for another 4-5 minutes. Put the spinach in a large salad bowl and add the bacon/leek mixture. Toss well, letting the warm bacon wilt the spinach. Add the sweet potatoes to the salad and toss together. In a separate bowl whisk the salad dressing ingredients. Pour over the salad, mix well.
