Make Ahead
The crabmeat and mayo mixtures can be prepared a day ahead and kept covered in the refrigerator until ready to assemble on tostadas.
Great Entertaining
This refreshing salad also makes a great appetizer. Prepare mixtures as directed, top tortilla chips with 1 tsp. of the mayo mixture and about 1 Tbsp. of the crabmeat mixture. Arrange on platter.
