Ingredients
- 2 sleeves Ritz crackers (about 7.5 ounces or 1 3/4 cup crushed crackers)
 - 1/2 cup grated Parmesan cheese
 - 6 tablespoons butter, melted
 - 1 large egg white
 - 6 ounces cream cheese, at room temperature
 - 1/2 cup good quality mayonnaise
 - 1/2 teaspoon garlic powder
 - 1 teaspoon apple cider vinegar
 - 3 cups freshly shredded sharp cheddar cheese
 - 1 (4-ounce) jar diced pimentos, drained and diced
 - 3 or 4 large heirloom tomatoes, sliced
 - Fresh basil leaves and minced chives, to taste
 - Kosher salt
 - Flaky sea salt
 
Preparation
- 
Preheat oven to 350 degrees Fahrenheit.
 - 
Add crackers to bowl of food processor. Process until crackers are a fine crumb. Add Parmesan cheese, melted butter, egg white and 1/2 teaspoon kosher salt. Process until evenly combined and mixture holds together when pressed between fingers. If it doesn’t hold together, add an additional tablespoon of melted butter.
 - 
Tightly press mixture into bottom and sides of 9-inch tart pan with removable bottom. Tip: If the crust is not packed tightly, it will crumble when sliced. Use the back of a measuring cup to help really pack it down, as seen here.
 - 
Place tart pan on a baking sheet and bake until golden brown, about 12 to 15 minutes. Set aside and cool completely. Then place in fridge for one hour to help crust set.
 - 
Meanwhile, add tomato slices to paper towel-lined plate. Season with kosher salt and let sit for a few minutes to remove excess moisture.
 - 
Mix together softened cream cheese, mayonnaise, garlic powder, apple cider vinegar and 1/2 teaspoon kosher salt. Whisk until evenly combined.
 - 
Stir in cheddar cheese and pimentos. Check for seasoning and add more salt if needed.
 - 
Spread pimento cheese mixture evenly on bottom of chilled tart crust.
 - 
Top with sliced tomatoes. Garnish with chives, basil leaves and flaky sea salt. Serve immediately.
