Ibn Ezra on Leviticus 7:13

על חלת. כמו ויבאו האנשים על הנשים והטעם עם חלות: WITH CAKES. The meaning of al challot is with cakes.²³In other words, the word al should be here rendered as with. The word al usually has the meaning of on. Hence I.E.’s comment. Similarly And they came, both men and (al) women (Ex. 35:22).²⁴Here too the word al has the meaning of with.
