The price of a baked potato at a restaurant is stupid high. Unless you don't have an hour. Then the price is completely reasonable. It sucks. But if you have an hour you can make a baked potato. Two even. And make them very unhealthy with toppings.
Cost per person $1.01
And make them very unhealthy with toppings.
I've been subbing in Greek yogurt for sour cream, and I no longer taste much difference. Some would call it blasphemy, of course. I've found that dried chives (unlike dried cilantro) work pretty well for sitchy-ashuns like this, too. Then there's a sprinkling of nutritional yeast and dried roman / parm, which... is a healthy but pitiful sub for that delicious-looking cheddar there, lol.
As for a fried bacon alt, luckily for me with my fridge still on the fritz, the local super recently put packs of uncured turkey bacon on sale, so I've been grabbing them up. $2.50 for a pack of 14 slices (3oz) where they're normally at ~$7. They store at room temp indefinitely, and kinda taste like a cross between fried bacon and jerky.
The image is enormous, so I don't want to paste it in:

EDIT: Maybe a solar oven to help replace the fuel / electric cost of one hour of oven's use?
