Yeah but slightly different if you use a dedicated toastie maker which are pretty common, it seals the bread around the edge and gives you a perfect pocket of cheese.
if you ever feel so inclined, all you need to make your own tortillas at home is:
masa flour aka specially treated corn flour
a stovetop and a pan for cooking
a plastic food storage bag
something with a flat bottom, ideally transparent
water
the bag of flour typically has instructions for how much flour and water to mix. you can mix it by hand and form it into balls by hand. the size of the balls only matters if you care about the tortillas being "the right size".
From there, you press a ball flat, toss it on an already hot pan over medium heat, flip it after a couple of minutes, and remove it after a minute more. to press the ball flat, place it under your flat-bottomed transparent thing and mash on it until it looks tortilla-shaped enough for you.
the plastic food storage bag is optional/recommended to stop the tortilla balls sticking when you press them. cut the food storage bag open along its seams and remove its zipper if it has one. what you have left is a single sheet of plastic with a seam/hinge in the middle.
it might be sounding like a lot but it's really just:
mix flour into wet balls
mash flour in your "press" made of random flat dishes and a plastic bag
cook the thing a little
eat
if you iterate on those 4 steps a dozen times, you'll be out like 50 cents of flour and you'll have produced at least one satisfactory tortilla. and it'll be so, so much better than store bought, you'll think about it every time you have store bought tortillas therafter.
Ah, I meant wheat tortillas. I won't tell you what I think of maize tortillas in case you get upset. I don't think you can even buy the ingredients you mention here.
