He did not want the toast

You could make some crutons.

I put left over toast into my toaster oven and bake at at very very low heat until it is completly crispy this can take some time but makes the best bread crumbs for breading meat or fish.

You could butter it, cut it into little cubes, sprinkle with garlic salt and bake it till it's crispy and have croutons for a salad. You can also bake it till it's crisp and crumble it to sprinkle over a tuna casserole the last 5 minutes of baking for some nice crunch.

Feed it to the birds

I never had white toast as a leftover before... whatever leftover i have... i just eat them the following day... by adding them to my soup or as garnish to my fried rice... but i think if i had that sort of food in my fridge... i will just heat it up and eat it as a snack... but i will add butter or cheese or jelly to make it more tasty...

OMG...I just got entirely lost reading this. You were going out and yet planned on cooking pork stew and rice but then had company and then on to how you make it but didn't? And then why not spagetti cuz you had macaroni and the beans and weiners and all this to ask...what to do with toasted white bread? Sorry...I'm blond and this just struck me funny...maybe because usually it is me that would write something this confusing. Ok to your question...what to do with the toast...I'd just throw it out.

There are quite a few things you can do with it...
1) Grate it up to use as a topping the next time you make macaroni and cheese.

2) Make small cubes and toast them in the oven for croutons for a salad.

3) Freeze any unused white bread or taost to use in making stuffing for
chicken, turkey or stuffed pork chops.

Those are a few I can think of, anxious to read your responses and see if there are more ideas.

Beat a few eggs in a bowl large enough so that the beaten egg mixture covers the toasted white bread and then allow the bread to soak until soft, or at least softer. Next, melt butter at a low heat in a frying pan and make french toast. Then feed it to some birds.

You also might consider beating your food-retard of a husband to a bloody pulp with this leftover bread, and then when he is nearly unconscious, about to black out and in the throes of a hallucinatory state, force feed him the leftover toasted white bread crumbs and whisper in his ears, left ear right ear left ear right ear, pushing him deeper and deeper into a delta mindset, repeatedly, insistently, "This is vegetable matter, this is vegetable matter, you are eating vegetables, vegetables are eating you, you are vegetable matter."

And the next time the minister of your church stops by unannounced, pretend you're not home until he goes away.

Or perhaps you could just eat dinner later, like at midnight, or not at all.

I've used leftover toast as croutons in salad or soup. I like to cut it in cubes and rewarm it in the toaster oven, maybe seasoned with a little garlic powder.

I wouldn't even think about what to do with it as I would bin it. Maybe now I'm started to be more frugal then I would use it as croutone in soup. Sorry, I am just not that imaginative. I am sure that others will come up with something better than this poor effort! Blessings
