Place 1 cup of water into a small pot and bring to a boil.
Add the lentils and let boil for 1 minute.
Reduce heat to low, cover and let simmer for about 45 minutes until the lentils are completely cooked through.
Pour water into a pot until it is about 2" inches deep and bring to a boil over high heat.
Place the sweet potato into your Sage Baby Eco-Steamer and put into the pot.
Cover and steam for 10-12 minutes, until the sweet potato is fork tender all the way through. You can either steam the spinach with the sweet potato or leave it raw.
Using your Sage Baby Puree & Blend food processor or immersion rod, blend the sweet potato, lentils and spinach until desired texture is achieved. For Stage Three, we recommend a chunk-a-licious consistency - thick and lumpy with soft chunks to help baby learn to chew. Avoid any hard chunks.
