I apologize in advance because this is a recipe of approximates- the roasted red peppers are a food I've been eating all my life and are a staple in Yugoslav cuisine; we have never had exact measurements for this recipe. For the crostini, I like to use a substantial bread like a French baguette or Italian loaf (I used Trader Joe's sliced Italian loaf for these in the photo but will use any hardy bread that is handy). If you can't find buffalo mozzarella (I buy mine at Costco), you can use regular fresh mozzarella. For the roasted peppers: red peppers (however many you want to make) plain white vinegar chopped garlic- lots of it extra-virgin olive oil First you roast the red peppers over the grill until they are charred everywhere. Put them in a glass bowl and cover them with a plate or foil and let them steam until they are cool enough to handle- this can be as little as 30 minutes if you have tough fingertips from perpetual kitchen burns like I do...
