A few tips:
Even after being seeded Jalapeno's pack a bit of a kick. If you are serving to a group and are unsure of their tolerance levels, you could always switch to pickled jalapenos or even reduce the amount by making half the baguette the spicy side and the other without. This way everyone will enjoy the dish you've prepared!
I've garnished very simply with mashed avocado but you could also serve on the side some freshly chopped cilantro and perhaps your very favourite hot sauce? :)
Why the broiler? For me personally, I like the inside of the loaf to still have a bit of softness and chew, broiling simply puts a crisp on the top. You could always bake if you prefer the whole loaf to be nice and crispy but do so carefully as it can burn quite quickly.
