Raid the Convenience Store

The hosts are invited to shop (for free) at a convenience store within a time limit and can only use a small shopping basket. They are expected to use 20 minutes to make an appetizer and entree using the microwave and small cook pots in the convenience store.
The guests would be taste-testing the dishes and decide who would win the show. The winner can shop all they want with a golden basket, with all the expenses being paid by the production team.
