“You don’t have enough sandwiches on your blog,” my father declared a few days ago. “Wadaya mean I don’t have enough sandwiches? I’ve got plenty of sandwiches,” said I.

Dad proceeded to rattle off a list of sandwiches he likes that he couldn’t find on the site, ending with, “and you don’t even have the arugula focaccia sandwich!” as if given how much arugula we grow around here the very omission was a sin of the highest order.

“Can’t do anything about that dad, arugula is out of season.” A little while later my father went out and returned with some freshly baked focaccia bread, tomatoes, mozzarella, and a bunch of arugula he foraged from Whole Foods.

The pain of spending $2.50 on a handful of arugula that grows like weeds half the year in our garden was not lost on him, or me for that matter. “Oh, the sacrifices I make for your site,” he joked, adding, “Tell your readers they can substitute watercress if they can’t find arugula.” And there you have it.

    What vinegar would you recommend to substitute the red wine vinegar? Thanks!

    Elise can you grow arugula in a pot??? I don’t have a yard, I grow some herbs in the pot and would love to grow arugula if it will survive. I know it’s so expensive everytime I bought it at Wholefoods.

    John: Yes, any veggie or herb can be grown in a pot. Be careful of your fertilizing & watering (check a garden book on containers, or ‘square-foot-gardening’). My Mom used to grow tomatoes in the house (use a small art brush to polinate the flowers), and we’d have hot-house tomatoes in winter!

    Mayonnaise!!!! Its gotta be a nice drizzle of olive oil…..

    Hi Trishinomaha – keep saying how handsome my dad is and he’ll keep cooking forever! He loves reading comments like that. ;-)

    Ethan and Dennis – aioli would work, some really good olive oil too

    Regarding growing arugula in a pot. Never tried. We can’t get rid of the stuff. We ignored our patch for years and it reseeded itself over the entire garden. It is a very hardy plant, I would say, go for it.
