We love sardines
We love sardines. My 8-year-old son would eat sardines straight out the can, without anything else. Last year, he begged me to put sardines in his lunch box. Knowing his friends would tease him, I warned him but he didn't care. He loved sardines that much.
If eating straight sardines seems gross to you, you can try cooking ( more like heating) it with some herbs and spices to eat with cooked vegetables. I love to stir fry vegetables in a bit of coconut oil, season with salt, pepper, ginger, garlic, and curry powder. Once the vegetables are cooked to the right texture, I gentle pour in the whole sardines (I used sardines in tomato sauce or in chili sauce). Let it sit there and cook for a bit, sprinkle more fresh herbs and spices if I feel like it. DH doesn't like sardines as much as we do but he can tolerate the dish much better when I add ginger and garlic into it.
We don't eat sardines on crackers too often but we love to roll whole sardines in bread. Using a rolling pin, I roll a piece of bread flat like a tortilla. Butter it up, line two pieces of tomato sardine in the bread, plus a slice or two of avocado, roll up the whole thing like a sushi. Slice into small rolls and dip into tartar sauce or salsa. Makes a very good snack.

Another thing you can try is to make sardine omelet. Beat some eggs, add a bit oil, salt, pepper and whatever you normally put into your omelet eggs. Stir fry some peas and corn with seasonings, pour the beaten eggs all over the vegetables and cook until the bottom begins to firm up. Put whole sardines pieces in the middle, add spices if desire, sprinkle fresh cilantro or parsley over sardines, add shredded cheese of your choice over everything. Fold up omelet and cook until done. Server with salsa.
We love sardines and would eat them any time, anywhere. But for those who haven't eaten a lot of sardines, it will take a while to get used to the taste and smell. Once you're used to it, you will be hooked.
