@skinnylatte I will always remember the sandwich my French "mother" made when I was on a school exchange in high school (age 15): a huge swath of butter on a baguette, then meat and cheese (etc.). Best sando ever.
The thought of oil instead of butter in the quiche makes me twitch. Fat is not the enemy: imo portion size is (and sugar/sweeteners). I lost a bunch of weight in the past 8 months eating (healthy) full fat foods, but weighing portions.
