Here is a suggestion. Use Leila Fletcher to learn music reading, theory and technique and use Suzuki methods below only for the purpose of supplemental pieces. There are 2 famous easy Bach Minuets in G major. They are both in volume 2. The Suzuki methods below have a great selection of beginner pieces. Good luck.
