This is really just dressed-up guacamole. Instead of a dip, we’ve turned it into stylish, easy-to-eat cocktail bites topped with your own homemade oven-dried tomatoes.
Packages of crispy cocktail cups called “croustades” are sold in many supermarkets, often beside cocktail breads or appetizers. They’ll keep in a cupboard for months.
Roast tomatoes. Cool, then cover and refrigerate up to 2 days. Make avocado mixture up to 5 hours ahead and refrigerate. Up to an hour before serving, fill cups and garnish with tomatoes.
