Make the dressing first so the flavors have a chance to marry before being introduced to the salad. Measurements are not given, start conservative with a pinch or so, taste and adjust to your palate.
Good quality Olive Oil (usually the most expensive you can buy)
Red Wine that you like to drink
Usually the ratio is 1.5 parts oil to 1 part wine but recipes vary from 2:1 to 1:1.
If you are using the whole recipe immediately, fresh garlic adds a nice bite but it will continue to flavor the dressing for as long it stands and might overpower the flavor in any leftovers. I like to use roasted and dried garlic. Do not use garlic salt or garlic-flavored anything, garlic granules are fine if the ingredients are simply garlic.
Since I can't tolerate raw onion (bah! humbug! I want my onion!) I didn't put any in the salad itself. I did however use dried onion flakes in the dressing. Other flavor agents I used were dried oregano, dried basil, and the contents of one or more teabags Traditional Medicinals Pregnancy Tea (you could use dried peppermint instead). Celtic Sea Salt and ground black pepper rounded out the dressing. Shake to combine.
For the salad itself, I used a "power greens" bagged salad of baby spinach, baby kale, and baby red chard, chopped slightly. Then I added diced and seeded cucumber, diced grape tomato (or diced and seeded if you use larger roma tomatoes), sliced black olives, and crumbled feta cheese. For people not me who can eat onions, add thinly sliced red onion.
Slice cold cooked steak (mine was leftover from last night's dinner) across the grain.
To assemble, pour a tablespoon of dressing into a large mixing bowl (seriously, this is plenty of dressing for three dinner salads or up to six side salads!), add all the ingredients except the steak on top of the dressing. Using tongs, or for best results, your own two hands, toss the contents of the bowl until well coated with dressing. Add the steak and repeat. The two step process helps to mix the salad fully before the larger meat pieces throw off the weight distribution, which would make the salad not come together as well.
Serve with saffron rice, lemon-garlic roasted potatoes, or toasted pita points.
