Three essential elements have formed the tuscan gastronomic traditions: 

The "poor" peasant tradition with the emphasis on bread soups, vegetables, beans and eggs, with very little meat.

The middle-classes cooking probably is very similar to today's.  

The aristocratic cooking which, due to Catherine de' Medici,  influenced French cooking.
 
Fundamental ingredients are:

Bread - unsalted, well-baked with crust

Extra-virgin olive oil

Grilled meat

Fresh vegetables

Wine ( Chianti )
 
Obviously such a simple and natural cooking depends on the freshness and quality of the ingredients.
