Where I come from, rural folks would have their largest meal mid-day, and call that "dinner", with supper being the evening meal.
Now most people have their main meal in the evening, and dinner and super are used interchangeably.
But I had my dinner today about 1 pm.
A nice bacon-wrapped filet mignon, with Montreal steak spice, fusili pasta with pesto, and sunflower sprouts very lightly sauteed with butter and garlic and dressed with a little lemon. A nice glass of Australian Shiraz to wash it down with.
This was my first time having sunflower sprouts, a gift from a neighbour's garden. The are absolutely delicious.
