Sardines are the kind of food that people scoff at but they are actually very tasty and a great and cheap source of protein.  
Here they are with sliced jalapeños, chopped parsley and lemon. 
They are also great with mustard and lemon and lots of black pepper. 
Also roasted red peppers. 
Also mashed on toast. With avocado and tomato. 

Some people use them instead of tuna in tuna recipes.
