- Stews, curries and similar foods are enriched by remaining frozen for some time. It seems to allow the flavours to mingle, or something.
- Making large batches of food is far more efficient than making food on demand.
- Industrial production of frozen food is far more efficient than any resteraunt can hope to be.
- Cheap takeaway food is typically low in quality, offers poor or medicore nutrition, and can take a long time to be delivered.
Create a franchise which specialises in defrosted high-quality meals.
By being more efficent, can offer more tasty, more nutritious, faster-delivered meals at same price as bad quality takeaway.
Hire chefs who know what they are doing to figure out how to industrially produce high-quality meals that are well-suited to freezing. Focus on flavour and nutrition.
Production can happen anywhere in the world, whereever is most cost-efficient. Use fresh, quality ingredients.
Ship the frozen meals to distribution centers in metropolitan areas.
Distribution centers should be small, simple operations. Their job is re-heat the frozen meals (perhaps also offer simple accompaniments e.g. rice, bread). The idea is to remove the usual costs of running a kitchen.
Leave other options to franchise owners (choice of accompaniments, ability to customize/modify meals etc.)
Result: a food service which offers less choice than a normal takeaway restaurant (given the constraints of freezability and simple preparation), but offers better food, delivered faster, for at or lower than current prices of low-end of takeaway food.
Edit 2013/12/01: May work better as bulk food delivery service, prepare and freeze as above, deliver in bulk e.g. minimum order 10 units. Quality frozen food for lazy people. Even lower overheads.
