Preheat the oven to 180C/350F. Line a large baking sheet with parchment paper and set aside.
Place your tortilla chips on the baking sheet, followed by the shredded cheese, and half the salsa. Transfer the sheet into the oven and bake for 10-12 minutes, or until the cheese has melted.
Remove the nachos from the oven. Top with spoonfuls of guacamole and the cheese sauce. Sprinkle the freshly chopped vegetables on top, and drizzle with sour cream. Serve immediately.
Notes
Tortilla chips: You can use store-bought keto tortilla chips. Quest tortilla chips yield 4 grams of net carbs per package. One serving equals my entire keto tortilla chip recipe. Leftovers: Keep in the fridge, covered, for up to 3 days. Remove the avocado. Reheat in the oven to keep the chips crispy.
