Place lentils in a fine mesh strainer and rinse well under running water. Combine rinsed lentils and 1.5 cups of water in a medium bowl and soak for 30 minutes.
In a dutch oven or large soup pot add the olive oil and heat on medium until oil is hot. Add onion, garlic and ginger and cook, stirring frequently, until the onions are translucent and tender.
Add mustard seed, coriander, cumin, turmeric, chipotle chili powder and hot curry. Continue cooking, stirring frequently until fragrant, approximately 3 minutes.
Add lentils and their cooking water, tomatoes, honey, sea salt and pepper and stir well. Cover and reduce heat to a simmer for about 30 minutes, or until the lentils are fully cooked and tender.
Stir in lime juice.
Blend using an immersion blender or regular blender or food processor (in small batches) until desired consistency is reached.
Serve hot or cold as a stoup, spread for crackers, wraps or sandwiches, or as a dip for fresh veggies.
