Directions :
1. In a blender, add tomatoes, garlic, 1/4 onions, serrano pepper, chipotle and 1/4 cup of water. Blend and reserve.
2. In a large pan* saute remaining onions over medium heat until translucent.
3. Increase heat to high and add ground beef. Brown the meat until it is lightly cooked and no longer pink. Season the meat with salt, cumin and oregano and pour blended sauce over it.
4. Add potatoes, carrots, bay leaves and decrease heat to low. Simmer for at least 20 minutes, until potatoes are cooked through and sauce reaches desired consistency. (I usually simmer for 40 min to an hour). Add water if necessary.
Enjoy !!
