I have become a fan of salad in a bag. It's so easy to rip open a bag of lettuce and add whatever suits your fancy. And one that I would recommend is the "cheap" $1.29 bag of Classic Iceberg (Dole) from Raley's. Yes, I said iceberg, and although that's usually not the most interesting salad around, the Dole bag has added purple cabbage and slivers of carrots. It's actually colorful before you start adding your favorites to it.
This evening I added chopped red onion, cranberries, tomatoes, yellow banana peppers, cantaloupe, walnuts and some avocado...excellent! And think about it; $1.29 and it lasts us for 3 meals.
