Iftaar (Breaking of Fast) after Ishaa prayers is highly desirable, preferably with water, milk or dates.

At the time of Iftaar:
(1) Recite the following dua'a:

[O my Allah, for Thee, I fast, and with the food Thou gives me I break the fast, and I rely on Thee.]

(ii) Ameer ul Moo-mineen Ali ibna Abi Taalib (A.S.) used to recite the following dua'a before Iftaar:

[In the name of Allah, O Allah, O Allah, we fast, and with the food Thou gives us we break the fast, an obligation we fulfill, and Thou are Hearer, Knower.]

(iii) While taking the first mouthful recite:

[In the name of Allah, the Beneficent, the Merciful, O He whose indulgence is boundless, forgive me.]
