Preheat the oven to 400F and line a baking sheet with parchment paper
Thinly slice sweet potato into rounds and coat with olive oil, paprika, curry powder, and garlic in a bowl. Add salt/pepper to taste
Bake sweet potatoes for 20 minutes, flipping once half way. Then broil for 2 minutes to get crispy (keep an eye on them to make sure they don't burn!)
While sweet potatoes are cooking, dice the tomato, red pepper, avocado, and jalapeno
For the crema, add all ingredients to a food processor and combine until smooth. If you want a thinner consistency, add 1 tablespoon of water at a time and blend.
Assemble nachos! Layer sweet potatoes, load with all your toppings, and drizzle on the avocado crema! Option to top with yogurt and sriracha if desired.
