This will depend on the chorizo you use. Some chorizo sausages are much spicier than others - so if you're worried, look for one that's labelled as being 'smoky' rather than spicy. You'll also use chilli in the pineapple salsa. It's only 1/2 a chilli and it's offset by the sweetness of the pineapple and the tomatoes so it's not overpowering, but you could skip it, or reduce it if you're worried.
