First, prepare sweet potatoes by grilling or steaming them
Peel and place steamed sweet potatoes in a bowl and crush them finely using a fork or mash.
Make it when you have steamed sweet potatoes left.

Add chopped onion 3, paprika 2, chopped pickles 2, and corn 6 to this.
You don't have to put in the ingredients that aren't there.
I added corn for a chewable texture, and you can add nuts or raisins to it.
For your information, I used steamed corn grains.
Can be replaced by canned corn sold in marts

3 mayonnaise, 1 Parma cheese powder, 0.3 sugar, and a little salt
If you add Parma-san cheese powder, it's very savory.
And if the sweet potato is high in sugar, you can skip sugar.
Apply it to the sweet potato you have and make it delicious.

Now mix all the ingredients well.

Hot dog bread is left in an electric rice cooker without baking it.
I think I put it in the freezer for about 5 minutes because it's bread.
It's so soft that it's delicious even if you just eat it
Now, put a lot of sweet potato salad in between the breads, and that's it!

Sweet potato sandwich is done
If you think bread is too much, you can just eat sweet potato salad.
It's a shame that the nuts didn't come off.
If you have nuts at home, make sure to put them in your salad.
Then it's more savory and delicious.
