Roasted Sweet Potato Salad with Spinach and Avocado

I started making some sweet potato fries for dinner, and then realized I had some spinach and avocado and thought they would all be tasty together. And sure enough, I found a recipe online. I modified the recipe a bit, used the same dressing, and it turned out great. I really liked having the warm sweet potatoes and nuts on the fresh spinach. To make this EVEN easier, you could use any bottled dressing, or one without tahini and it would still be good.

2 sweet potatoes, diced
small onion, diced
coconut oil
4+ c spinach leaves
1 avocado, diced
1/2 c almonds, toasted
feta cheese (optional)

Dressing:
2-3 T tahini
1 T water (i used hot to soften the tahini)
1 T olive oil
juice of a small lemon
salt to taste
garlic, minced (optional)

Roast sweet potatoes and onion in coconut oil at 500 degrees for 15-20 minutes, stirring halfway through. Mix dressing and toss with roasted sweet potatoes/onions. Layer sweet potatoes, almonds, and avocado over spinach and serve!
*Note that in photo i just put dressing over the top...I think it is better mixed in with the potatoes, but I didn't get a photo!
