preparamos

We use that form of the verb to agree with the subject which is first person plural. Sarits y yo (we) preparamos . . .
preparamos
Preparamos because the subject, Sarits y yo, is plural and includes yo. This means that the nosotros conjugation of the verb is needed. Preparan is ellos or ustedes.
