Dave,
I don’t know that sandwiches are necessarily economical, but they can be. That being said sandwiches are just about my favorite food of all. If I had to choose to only be able to eat one thing for the rest of my life it would be sandwiches, provided I could have a variety of them.
Every Friday is sandwich night for dinner in our home. Either Grilled Ham and Cheese, Tuna Melts, BLT’s, BLAT’s, Egg Salad, Tuna Salad, Turkey, Ham and Cheese, Club Sandwiches, Salami, you name it I make it. Every day for lunch I make one sandwich that we both split, since at our age we don’t need a big lunch. I bake all the bread in our home mainly because homemade bread is just better for sandwiches.
Looks like you like a variety of sandwiches too. Enjoy!
Eddie
