Yes! You can eat crab apples! They’re super cheap and, despite their super tartness when raw, are sweeter than regular apples when cooked. The best place to find these is at your local farmer’s market (or on your neglected apple tree). If you can’t find crab apples, one or two regular apples work too:).

Bring water, oats and salt to a boil in a covered medium-sized saucepan. Once to a boil, uncover and cook at boiling for about 2 minutes and then turn heat to low.
Add the crab apples apples and banana. Cook for 15 minutes, then add spices and raisins.
Cook another 10 minutes, or until oats are cooked and most of the water is absorbed. Turn off the heat and stir in nuts.
