The first one is correct. "Makes" is the verb, "it" is the object of which "makes" refers to, and "easy" is the adjective. "It" refers to the work done to prepare the meal. However, referring to the work in general is informal English and can be improved by expanding upon the aspect of work that has been made easy. The word "nice" is much more professional than the word "good." "Good" implies that the meal would not be appetizing if it were not for the Spanish cooking. However, the word "nice" implies that the meal is enjoyable to eat in general because of the Spanish cooking.
The phrase, "Make easy" is an expression used to mean, "to get along with again," or, "to resolve." When people say, "Let's make easy," it is usually after a conflict between two closely related people and is said by an outside party.
