Avocado and goat cheese with lemon juice, salt, pepper, and cayenne (can adjust spices to taste, I see recipes online that use cumin instead of cayenne)
Reuben dip - this can get expensive because of the corned beef (we stock up a bit around St. Patrick's day when there are sales), but it's delicious
Taco dip - mix cream cheese, sour cream, and taco seasoning. Top with salsa and shredded Mexican blend cheese.
