Heat oil in a large heavy bottom pot or Dutch oven over medium high heat. ( see notes for Instant Pot)
Add shallot, ginger and garlic, and reduce heat to medium to prevent burning, stirring frequently about 3 minutes until fragrant and golden. Add spices, seeds and salt and lightly toast, while stirring 1-2 minutes, which will enhance their flavor.
Add diced tomato, cook 2 more minutes, then add the coconut milk and stir to incorporate, bringing to a simmer. Add cauliflower and red bell pepper, give a stir, cover and let simmer 10-12 minutes on medium low heat. Check the cauliflower – it should be just tender, and continue cooking uncovered until desired tenderness (the smaller you cut the pieces the faster this will cook). Taste, add a squeeze of lemon juice. Add more salt if necessary.
Serve in bowls over rice or with naan or pita bread. Garnish with cilantro.
