In a bowl toss sweetpotatoes with oil and ½ the taco seasoning packet. Roast the potatoes in the oven at 400°F for 20 minutes.
For Salad
While potatoes are cooking, prepare the meat and salad.
Brown the beef in a skillet until it is no longer pink. Add the taco seasoning and water. Allow the mixture to simmer and reduce.
Whisk the ranch with the salsa and set aside.
Place lettuce in two bowls. Top with taco meat, taco roasted sweetpotatoes, tomatoes, olives, cheese, guacamole, and sour cream. Drizzle the salsa ranch dressing over the salad. Top with crushed tortilla chips. Serve.
