1 (10 ounce) package mini twist pretzels
1 (12 1/2 ounce) box Ritz Bits miniature crackers (or Ritz sticks snack crackers)
1 (9 3/4 ounce) can salted cashews
1 (7 1/4 ounce) package bite-size cheddar cheese goldfish crackers
1 (1 ounce) package ranch dressing mix
1/2 cup vegetable oil
In a very large bowl, combine the pretzels, Ritz bits, cashews, and crackers.
(I use my largest roasting pan for this.).
Sprinkle evenly with dressing mix, then drizzle with oil.
Stir gently but thoroughly until all pieces are well coated.
Store in an airtight container.
