My grandma always made Triscuit "thingies”—a crunchy, creamy, savory appetizer—for every holiday gathering, and they disappeared lightning fast.
In a medium bowl, stir together the mayo, parmesan, sour cream, dried onion, Tabasco, and Worcestershire sauce until smooth. Cover and refrigerate for at least 1 hour or up to 3 days.
Set an oven rack to the upper position and line a baking sheet with foil.
Spread a layer of the cheese mixture onto 1/3 of the crackers, completely covering the tops of the crackers, and place on the prepared baking sheet. Broil until bubbly and brown, 2 to 3 minutes. Let cool for a few short minutes, then serve warm. Repeat as needed. Extra spread can be covered and refrigerated. Use within 3 days. Love the recipe? Leave us stars and a comment below!
