You'll find every variation. A gite that has a kitchen but also offers dinner/breakfast; a gite that had a kitchen and doesn't offer meals; a gite that offers meals but has no kitchen. I remember one municipal gite that had a kitchen and if you wanted meals they were available, but served in the restaurant on the town square. A few times dinner included an aperitif or a little Armagnac at the end, or both. Sometimes there's a restaurant nearby and sometimes not, but your choice of gite will give you some control over that. Once our only alternative to cooking ourselves was a restaurant several kilometers away that would send a car to pick us up as long as we had a group of 4. We formed a group of 5 and the chef and his wife came to pick us up.
Most of the time I stayed in a gite for 30 euros and got a bed, dinner, and breakfast. More expensive than Spain but also, on average, a far better value. Fewer beds per room, fewer bunk beds, better meals. On average of course.
One story: a hiker, I forget from what country but Anglophone, complained about the French breakfasts, just juice, coffee and bread and jam and a little yoghurt. He couldn't wait to get to Spain where it had to be better!
