Cut the beef into small cubes and add the chopped garlic and cilantro, mustard, Worcestershire sauce, seasoning, pepper, and salt. Let it marinate for an hour, refrigerating if possible.

In a skillet, add a little oil and place the beef. When it starts to change color, add the onion cut into strips and brown with the beef.

For the avocado cream, place all the ingredients in a food processor or blender with a little water to help blend everything well. You can add the lime at the end.
