Crostini can be made quickly and with whatever ingredients you have on hand. A great crostini starts with bread that’s been toasted (preferably on a grill or in a pan with a little bit of butter or oil) and sprinkled with salt. The toppings can be as simple as a spread of cheese or some jam, but you want more than that, right? Right. So here some of my favorite springtime crostini topping combinations to get you inspired.
