Stir together the cream cheese, 1/2 cup sour cream, and taco seasoning until smooth and well combined.

Spread the cream cheese mixture evenly over a large rectangular serving platter.

Top the cream cheese layer with a layer of salsa and chopped green onions.

Sprinkle the shredded cheese evenly over the top of the salsa.

Top the cheese with the shredded lettuce, leaving cheese on each end of the platter to form the end zones.

Transfer the remaining sour cream to a piping bag and cut the tip off the bag. Draw yard lines on top of the lettuce with the sour cream.
