Stir cream cheese, sour cream, creamy salad dressing, and taco seasoning together in a bowl until smooth; spread into a flat square or round dish. Spread salsa over cream cheese mixture layer; sprinkle with Cheddar cheese, tomato, green bell pepper, and green onions. Chill until flavors blend, at least 1 1/2 hours.
A solid layer dip - I didn't use Miracle Whip though (we don't buy that) I used mayonnaise. Actually, I could have left the mayo out and it wouldn't have mattered. I used red and yellow pepper...
