Yummy and super easy. I used goat cheese and substituted thinly sliced green onions instead of chives. Simplified a little by toasting the bread slices in the oven at 400, then roasted the asparagus drizzled with olive oil and salt & pepper for about 8 minutes (rather than blanching). Also wrapped thin strips of proscuitto around each stalk of roasted asparaus before placing on the toast.
This was absolutely delicious! The flavors in this recipe complement each other beautifully. I was really surprised at how good it was given the simple list of ingredients. I used reduced fat ricotta for the cheese and chives for the herbs. I think the lemon zest really gave it a good punch of flavor--I would not omit this. I could have eaten the entire loaf myself. Thanks for a great recipe Derf!
