Preheat oven to 350 degrees. Place a skillet over medium-high heat then add ground beef. Season with salt and pepper and cook until no pink remains, 6–8 minutes. Drain grease, return to stove and reduce heat to medium.
Add diced onion and cook 3–4 minutes until softened. Add milk and cream cheese. Stir until cream cheese is melted and everything is combined then remove from heat.
Add sour cream, taco seasoning, Worcestershire sauce and ½ cup of shredded cheddar cheese and stir until well combined. If desired, add a few dashes of hot sauce to bring up the heat level.
Transfer to greased pie dish then sprinkle with the remaining ½ cup shredded cheese. Bake 15–18 minutes until the cheese is melted and the dip is nice and bubbly.
Remove from oven, sprinkle with diced tomato, sliced olives and green onion. Serve piping hot with plenty of salty tortilla chips.
