I love Kua'aina's avocado sandwich so much so I decided to make my own version.After looking up the recipe I found that the real thing uses less seasoning than I do.I like stronger flavors so I added mayo to the ketchup and that's what makes it so delicious.Toast the bread before you use it to get that yummy toasted sandwich texture! The combination of ketchup and mayonnaise is the key to this recipe. Recipe by Marumochan

I usually eat onion and tuna-mayo in a sandwich, but my daughter likes it with cheese and for it to be toasted.The texture is best when the onion is finely chopped, but if that's a pain, you don't have to~It also tastes great on English muffin.It's so simple, there's really nothing to say!!

This is a basic sandwich that's often served in American diners and the like. Since it's easy to make at home I don't often order it when dining out. Whenever I do feel like eating one I make it for free at home.I used canned tuna in water this time. I also recommend using sour dough bread! You could also cook a tuna patty in olive oil and sandwich it between 2 pieces of toast, that way tastes pretty good too. Tuna melts don't normally contain avocado but I think tuna and avocado goes well so I put some in. Recipe by O mama ma

I made an easy pizza toast using microwaved potato and canned tuna.I went easy on the mayonnaise in Step 3, since I add a bit more mayonnaise as topping just before toasting this. Please adjust the amount to your taste! Recipe by Nanagukun

I came up with this easy tuna salad that can be served either in a salad or in a sandwich. While it's lower in cholesterol than ham or eggs, it's hearty and filling. Add ketchup to give a subtlety sweet taste!The salad will become creamy by mixing it thoroughly.Create your own taste by adding your favorite herbs or spices, such as Japanese mustard, whole grain mustard, thyme, rosemary, cumin powder, curry powder, etc... anything goes!

I love to experiment with Tuna. It's like eggs, so easy to use in many things. This was today's lunch for hubby, I haven't been eating as much due to morning sickness

We often make this tuna sandwich in my house.Adjust the quantity of mayonnaise to taste. Recipe by Kourin

I love tuna and often have it simmered with Chinese cabbage, but I wondered if it would be good as miso soup, too.You can use dashi stock instead of water + dashi granules of course. Since plenty of flavor comes from the tuna, you can probably use less miso than usual. For 3 servings. Recipe by HAL.M

I wanted to use canned tuna in something different for a change.The key is to add the soy sauce, sake, and salt before adding water. You can experiment with different seasonings. Use whatever ingredients you like!You could garnish with chopped leek or shiso leaves! Depending on what kind of canned tuna you use, it can be a bit salty. For easy to make amount. Recipe by Maca

Very tasty & healthy tuna sandwiches with Greek yoghurt and lots of onion! I'm very sure that the sandwiches with this recipe will satisfy your mouth!

I often hear busy people complaining that they want to be able to eat a proper meal in the morning but don't have time, so I came up with this recipe. This omelet can be made quickly with ingredients already on hand and is full of volume. The rich aroma of the 100% pure sesame oil will increase your appetite!Make sure to drain the liquid from the can of tuna. If you leave too much tuna in it, the omelet won't wrap up very easily. Heat the frying pan well before pouring in the egg. If you cook the egg too much it will harden, so be careful! It's best to combine the onion and tuna in a bowl beforehand. Recipe by Kadoya-seiyu

I love tuna casserole, however it can seem boring so I created this to shake it up a bit.
