Heat olive oil in a large saucepan over medium heat.
Sauté chopped red onion for 3–4 minutes until it gives up.
Add garlic, cumin, paprika, thyme, and stir until fragrant—think "spice drawer explosion."
Toss in sweet potatoes and lentils. Stir like a boss.
Pour in broth and water. Bring the whole thing to a dramatic boil.
Reduce to a simmer, cover, and cook for 25–30 minutes.
Stir occasionally so nothing clings like a bad date.
When lentils and potatoes are soft, remove from heat.
Add lemon juice for brightness and sprinkle with chopped herbs.
Serve warm with toast, crackers, or life advice.
