Heat up a large skillet on medium high heat and add in avocado oil. When the oil is hot, add in the ancestral beef blend and stir.
Add in the diced yellow onion, minced garlic, tomato sauce, cumin, dijon mustard, Worcestershire sauce, and salt and continue to stir and cook until the meat is browned (~5-6 minutes)
In a separate pan, cook your hotdogs in avocado oil using medium-high heat until they are browned and crispy on all sides (~4-5 minutes) and remove from the pan.
Assemble your Ancestral chili dog by placing the hotdog in a fresh hotdog bun, top with ancestral chili, diced red onions, raw shredded cheddar cheese, and chopped cilantro.
