Tips & Variations

For a creamier soup, use an immersion blender to partially puree the soup after cooking.

Try swapping lentils with chickpeas or black beans for a different texture and protein boost.

Add a can of coconut milk for a rich, creamy coconut curry flavor.

Use frozen mixed vegetables instead of fresh for convenience.

Include fresh or dried herbs like thyme, rosemary, or bay leaves for added depth.
