Preheat oven to 400 degrees.
Line a large baking sheet with parchment paper or foil, being sure it has a lip on all sides so the bacon grease won't drip off. Or you can use a broiler pan.
Lay the bacon on your prepared baking sheet and generously sprinkle both sides with pepper.
Bake for 7 minutes.
Meanwhile, line another large baking sheet with parchment paper.
Prepare avocados by cutting each one in half lengthwise, removing the pit, then carefully separating each half from its peel. Cut each half in 4 slices lengthwise and lay on the parchment covered pan. With a pastry brush, gently brush the avocado slices with half the lime juice.
When the bacon has cooked for 7 minutes, flip the bacon and return the bacon and avocados to the oven and bake another 7-10 minutes until bacon is crispy and avocados are browning on the bottom but still tender.
Remove from the oven and lay bacon on paper towels.
In a medium bowl, mash the avocados. You can use a food processor if you want or just use a fork. Leave it chunky or make it smooth, however you like it!
Add the remaining lime juice, crumbled bacon (leave a little out for garnish), minced garlic (2 or 3 cloves depending on how much you love garlic), sour cream, salt, and a dash or 2 of chili powder.
Stir until combined, taste, and add more salt/chili powder to get the flavor you want. Serve with your favorite gluten free crackers or chips!
