First, toss your slivered almonds into a small, dry frying pan and begin the toasting process over medium/high heat. Shimmy and stir those almonds around about every 30 seconds or so in order to toast each side. Keep a close eye on them, though, because they toast up pretty quick! Approximately five minutes. The amazing aroma of toasted nuts will let you know when they're just about done. Plus, they'll start to turn a nice golden brown color. Remove immediately from the hot pan.
Next, pull all of those gorgeous Bibb lettuce leaves free from the head and give them a good rinse. Pat them dry between two long rows of paper towels.
Once they're mostly dry, tear or chop the leaves horizontally to create 1 1/2 inch wide strips (give or take). Place in a bowl. FYI - This bowl will not be the serving vessel.
The next step is creating the dressing. In a small bowl, mix together a teaspoon or two of dijon mustard, seasoned rice wine vinegar and about 3 - 5 grinds of freshly ground black pepper. Give that dressing a quick stir with a fork.
Pour that dressing over your pile of lettuce. If you're choosing to add finely chopped mint, now's the time to sprinkle that in, too...
Then, give it all a good toss.
Use your tossing utensils to divide the salad into four small serving bowls, allowing any excess dressing to drip back into the mixing bowl before transferring over.
Next, add the blueberries, strawberries, avocado, and nuts.
The last thing you want to add is a light sprinkling of salt to the top of each salad. (I personally love the salt that you can grind in a grinder.) This will really help the ingredients pop, especially the avocado. If you're a fan of black pepper, add a touch of that to each bowl, too.
