Bring cream cheese and sour cream to room temperature by removing from the fridge 30 mins before preparing dip. This makes it easier to combine the two without getting lumps. Beat together cream cheese and sour cream.
Spread mixture in a layer approximately 1cm thick across the bottom of your serving dish. Refrigerate for 1 hour.
Layer with Salsa, Taco Beef (you can heat this up in the microwave if you want), cheese, lettuce and peppers
Serve with tortilla chips
