Heat some olive oil with a bit of mustard in a wok.
Add the onion, garlic, and chili peppers in sequence. Let them sauté for a few minutes.
Add the pumpkin, eggplant, and bell pepper. Stir-fry over high heat for a few more minutes.
Add the can of diced tomatoes, soy sauce, and water. Bring the mixture to a boil and let it simmer for about ten minutes.
Then add the remaining spices: rosemary, cilantro, paprika powder, ginger, etc. Mix everything well.
Let the curry simmer for another ten minutes until the vegetables are cooked and the flavors are well blended. Taste regularly and add more spices if needed. If too much water evaporates, you can add some more.
