Prepare all the vegetables by peeling and cubing sweet potatoes, chopping onion and bell pepper, mincing ginger and garlic. Add all these vegetables to a slow cooker.
Add the remaining ingredients, except for coconut milk, to the slow cooker.
Stir the ingredients together.
Set the slow cooker to high heat for 4 hours. Stir occasionally if possible (not necessary).
Once the curry is cooked (and lentils are soft through to the center), stir in a can of coconut milk.
Taste your curry and add salt (if needed) to get the right flavor.
Serve as-is or alongside a cooked grain (rice, quinoa, etc.).
Optional to top with chopped cilantro and/ or fresh lime juice.
