The winter term in France is slightly north of "mad." You trudge your way, in my case somewhat willingly, through 'les fetes"/xmas, new year...foie gras again, bottle after bottle of superb wines, jaw dropping calorific feasts.
Recall :Christmas day, a moment of heightened gastronomic excitement ( food version of multiple orgasm!) as I plunge my silver fork into my motherinlaw's asparagus pannacotta and take a sip of a 2007 dry white Meursault...I knew that if I tried to stand my legs would have simply crumbled underneath me such was my total total pleasure.Out the other side of this period and its a time when schools start really putting on the pressure - tests, exams, case studies. For "we, the teachers" its a race to write and grade exams, deal with students in crisis mode and those who have totally lost their motivation.
My belief is that its important to feed ourselves well to battle against the stress and winter fatigue. The busy factor doesn't really help most of us achieve this task. I have a back up of quick winter suppers which usually get my family through this period. Vegetable and protein rich, quick and economic.
