Need recipe help fast. What can I do with the following ingredients, that combines with yesterdays leftovers?

I would stick with the tomato sauce, the coconut milk might not be so good. You could add shrimp, but most certainly add sauteed onions with some garlic. I would not add additional spices from the original recipe, just use the ingredients that will make a little more of what you have and by adding shrimp it will seem like a new batch of what was probably an AWESOME meal.
