You can buy fresh or frozen. Frozen is a great option because the vegetables are frozen within hours of being picked.
Sweet Potato with Spinach and Peas
1 TBSP RAW Butter
1 small onion chopped
2 sweet potatoes, peeled and chopped
About 1 bag (1 cup) of Peas
1 bag of frozen spinach
My measurements are guesses since I used vegetables I froze from our food share!
Melt the butter in a saucepan and saute the onion for 2 to 3 minutes or until softened, the add the sweet potato. Pour in 1 cup of water (maybe more), bring to boil, then cover and simmer for 7 to 8 minutes. Add the peas and spinach and cook for 3 minutes. Puree the vegetables in a blender or processor to make a smooth consistency for your baby, adding a little of the cooking liquid if necessary.
I put my baby food in old baby food jars. The jars freeze well and I find that I have less freezer burn with the jars than the cubes.
This recipe made about 12 jars.
