I can believe that the Spanish consider fish, including sardines and tuna, packed in olive oil, to be a delicacy. I can believe this because these tiny Spanish sardines on these Piquillo Pepper and Sardine Tartines are absolutely delicious.  Top the sardines with roasted piquillo peppers, capers, lemon and sweet onion and you will create a beautiful bite.

Author Notes

Spanish sardines are a must for this tapas. I did try it with another type and found that sardines were very large and had a very strong flavor. These Spanish sardines are mild and they are tiny. I found them at Pisces Gourmet Seafood Specialty Shop on Yonge Street in Rosedale.
