自从我们是朋友 is very common in speaking, but it is mainly used for love relation, 自从我们交上了朋友 is a good old formal way to say that, but not popular those days. 自从我们成为了朋友 is the most used word in speaking and writing.

@Jacob Try to avoid leaving answers in the comments, otherwise you might find them deleted once they are deemed no longer needed.

@Jacob Really? I speak in Cantonese and I don't see that euphemism in daily speaking. The equivalent of 是 in Cantonese is absolutely fine in speaking. And I would write 是 in an essay. Though I'm not exactly brilliant at writing in any language though.

"Since" can mean "既然" (as) or "自从" (from the time)

"Since we are friends" is not translated as "自从我们是朋友". It is translated as "既然我们是朋友" (as we are friends).

"Since the time we were friends" is translated as "自从我们是朋友那時候起"

Your teacher is correct, "自从我们(是)朋友" is problematic because the verb "是" (is) doesn't has the meaning of "become"

"Since we'd became friends" should be translated as "自从我们**交上了**朋友" or "自从我们**成为了**朋友" (Since the time we'd **became** friends)
