Preheat oven to 450 degrees. Slice off the top of the garlic head, place it in the center of a piece of tinfoil, drizzle with olive oil, wrap, and place in the oven for 45-50 minutes. When done, remove from the oven and unwrap to cool.
While the garlic is roasting, roughly chop your bacon, and cook in a skillet until crisp.
When the bacon is almost done, add in the minced red onion and cook for 2-3 minutes. Remove from heat and set aside.
In a medium sized bowl, toss in the avocados and squeeze in all of the roasted garlic. (Should be a soft consistency) Add the lime juice and cayenne. Mash together roughly.
Stir in the bacon and onion mixture, as well as the chopped roasted red pepper, and cilantro.
