UNLEAVENED BREAD WAS USED FOR THE MEAL OFFERING

Leviticus 2:1 And when any will offer a meat offering unto the LORD, his offering shall be of fine flour; and he shall pour oil upon it, and put frankincense thereon:

Leviticus 2:4 And if thou bring an oblation of a meat offering baken in the oven, it shall be unleavened cakes of fine flour mingled with oil, or unleavened wafers anointed with oil.
