What to learn from a convert

Hello Rabbi. A friend from work, a traditionalist, decided to "get stronger" after his father's death. He and his wife started observing Shabbat, and he wants to set up a group with me once or twice a week to study Torah. He also feeds off the website and Torah readings of the Hidabrot organization, if you know the style.
He is not an educated person, nor has he sat down and studied anything since graduating from a vocational college. He knows almost nothing about Torah matters.
I am a yeshiva graduate, I know a book.
I'm really, really confused about what to study with him. Torah, Gemara, Laws, your trilogy 🙂
How do you start? Have you had any experience with a case like this?
