For topping: additional shredded cheese, crumbled bacon, and sliced scallion
Mix all ingredients in a medium bowl. Adjust seasoning to taste. Top with additional shredded cheese, bacon, and green onion and serve with potato chips.
BACON: I highly recommend making your own bacon crumbles here. I used 4 slices of thick cut bacon for this and it got me exactly 1/4 cup of crumbles. If you're using thinner bacon, I'd go with 6 slices. Cook diced bacon in a skillet over medium-low heat and drain on paper towels before using.You can make this up to 3 days ahead. Store in an airtight container until ready to serve. Be sure to set aside any toppings to use right before serving.
