First, make the candied pecans. Add the sugar, water and salt to a skillet set over medium heat and stir to combine. Bring to a simmer and cook for about a minute until the sugar and salt have dissolved. Add the pecans and stir to coat with the sugar mixture. Cook for another minute or so, stirring. Remove pan from heat and tip the pecans out onto a baking sheet to cool. Once cool, break up any clusters that may have formed.
For the dressing, add the lemon juice, olive oil and pomegranate molasses to a small jar and shake vigorously to combine. Season to taste with salt and pepper.
Put the baby spring mix, red onion, strawberries, feta, and cooled pecans in a large bowl. Add some of the dressing--about 3 tablespoons to start--and toss to combine. Taste and add more dressing if desired.
