Question

add a comma or semicolon if needed. otherwise, submit the text without any additional punctuation.
as quincy chopped the cilantro for the chili i shredded the cheese for the quesadillas.

Explanation:

The sentence "As Quincy chopped the cilantro for the chili" is a dependent clause, and "I shredded the cheese for the quesadillas" is an independent clause. When a dependent clause (introduced by "as" here) comes before an independent clause, a comma is needed to separate them for clarity and proper sentence structure.

Answer:

As Quincy chopped the cilantro for the chili, I shredded the cheese for the quesadillas.
