Selamat Makan!
Yummy! What a pleasure to eat in a warung (local restaurant). For a few dollars / euros you can eat a meal that is really satisfying.
There are some good places on the island, where you have a good Indonesian meal. Just look around, however, some restaurants less focused on the stomach west, so that the “Bali Belly” is not unknown.
If a good and safe to eat is Warung Murah (ie cheap restaurant) in Jl. Double Six (Bali). You can use the menu but I recommend that you order the buffet. Choose your type of rice (eg white or yellow) and choose your meat and vegetables. Enjoy the food and the price to be paid (yup, it’s cheap).
