I love sardines and eat them 2-3 times a week. My favorite are Jose Gourmet and I order them from Amazon. Their smoked trout is incredible too. Next would be Bella you can get them from Sprouts if you have one near you. King Oscar is a given since they are good and available everywhere. Another good mail order one is Nuri. I only buy ones in oil, the ones in water just aren’t as good. You might be surprised at how just a little squeeze of lemon will really perk them up. Hot sauce of course is always good. Sardine salad think tuna salad but use the sardines is very good.
