When fresh avocados are at their most expensive in the produce section of the supermarket, check out the frozen food section. Some supermarkets stock frozen avocado pulp, which is more economical.
2 large avocados
1 Tbsp lemon juice
1/4 cup chopped onion
1 small tomato deseeded, chopped
1 tsp salt
1/4 cup sour cream
1/2 tsp red pepper flakes
1 Tbsp cilantro
Slice avocados in half lengthwise; remove pits. Scoop out pulp with a spoon into a small bowl. Mash with a fork until smooth.
Add lemon juice, onion, tomato and salt to bowl; mix well.
Add sour cream, red pepper flakes and cilantro to bowl; mix well.
Spoon guacamole into a serving bowl. Serve with tortilla chips or quesadillas.
A cut avocado turns brown quickly when exposed to air. To help keep it green, sprinkle the exposed surface with lemon juice and cover tightly with plastic wrap.
