This question is pretty straightforward. Are there ways to take a sliced slab of bacon (i.e. a whole large package) and effectively cook all the slices to be used in standard scenarios, like breakfast? Non-microwave methods are strongly preferred.
It really depends on how you're planning on using the bacon:
If you're going to be crumbling it anyway, you can cut it across the strips, and drop it into a pan and slowly render it, then turn up the heat to let it crisp. You might also need to drain the grease part way through.
If you're willing to take a loss in flavor ... you can separate it into slices and simmer it. It won't crisp up, but you can par-cook it, and then finish it using some other method.
If you have the time & equipment to sous-vide it as moscafj mentioned, I suspect you'd get a similar effect as simmering, but wouldn't lose as much flavor. I'd also recommend splitting it up some to increase the surface-to-mass ratio as much as possible while still fitting in the bag, to decrease the cooking time.
If you want strips, the easiest bulk method is cooking it in the oven. If you have multiple sheet pans and cooling racks (or use a broiler pan), you can cook a whole pound of bacon at once. It can take an hour if you're cooking it slowly, but it's mostly unattended. (although using a broiler pan requires flipping them over a few times).
If you do go with the simmer method, save the water for some other meal later (eg, beans & rice).
Cooking bacon at high temperatures causes the fat and muscle to contract at more divergent rates, yielding crinkly bacon. Plus, bacon has plently of fat, none has to be added! So, for large batches, I usually just place a large wire wrack of bacon in the oven over a pan to catch the drippings. 425 F for 20 minutes, plus/minus 2-3 minutes depending on the cut thickness.
Try a double griddle. The middle is not going to cook as fast but just let it cook a little longer. As you lay them down you can overlap a bit as they will shrink. Overlap with fat side on the grill for faster shrinking. Start on far side for less grease splatter on you. Thick slices will be less slices for the same weight.
