Preheat oven to 400°F.
Wash and dry the baby red potatoes.
Place potatoes on a baking sheet and bake for 25 minutes, or until fork-tender but still holding their shape.
Remove from the oven and let them cool completely.
While potatoes are cooling, prepare the filling.
Add softened cream cheese, feta cheese, garlic, lemon juice, and pepper to a food processor.
Blend until the mixture is smooth and whipped.
Taste and adjust seasoning if needed.
Once potatoes are cool, cut each one in half lengthwise.
Use a small spoon or melon baller to gently scoop out a small well in the center of each half.
Spoon or pipe the whipped feta mixture into the center of each potato half.
Top each deviled potato with a generous pinch of crushed blue corn chips.
Arrange on a white serving platter.
Add lemon wedges around the platter for garnish, if desired.
Serve immediately or refrigerate for up to 4 hours before serving.
