Is there a local food pantry near you? As a diabetic, there are some foods you cannot scrimp on, e.g., fresh fruit, vegetables, lean meats / fish, healthy oils (especially extra-virgin olive oil) and coffee / tea. Perhaps a local food pantry can help you with some of these essentials. I am a big believer in rice and beans! I also like eggs and baked potatoes. Stock up on sweet potatoes and yams. Add fresh onions to as many foods as possible - especially to veggies. Cabbage is often inexpensive and is very healthy. A diabetic friend of mine swore by fresh tomatoes.
