>grandma has amazing pie crust recipe >everyone we know

Look at what other small scale food production companies do. You just get your stuff in local stores and spend zilch on advertising. There's basically no marketing involved. That's the first step before getting into large supermarkets. If you don't have locally owned non-ethnic supermarkets in your area, you're probably out of luck, short of selling at farmers markets.

No. Because the second you are noticeable, Pillsbury will do the same thing and out market/produce you.

Pastry has hardly anything to do with the recipe and everything to do with decades of experience making dough. Unfortunately this doesn't scale well and its a pretty specialized offering. Also, there are probably shops in your city already selling pastry dough. Finally, you have to meet food handling, production and packaging laws.

Selling whole pies would probably add more value but I don't really see this as viable friendo

You make a frozen pie crust, or possibly a refrigerated pie dough. You'll need to set up your business, make the product (you can often rent an approved kitchen) and package it.
You then do a demo roadshow at Costco or Sam's Club. Contact the manager a few weeks ahead and show them your product and hope they are willing to try your product. If they are, you can set up a little stand and bake some pies right there in the store, give samples and try to sell the shit out of it. As long as it continues to sell the store will continue stocking it.
I don't think I would do it, high risk, hard work, generally little money, but that's up to you.
I used to work for these guys who did the same sort of thing:
