When making layered mason jar salads, you put the ingredients in the jar in a specific order to keep everything fresh and separate, without getting soggy layers.
Start at the bottom with your dressing. You’ll want to add your protein to the dressing, or another ingredient that can withstand sitting in the liquid.
Next, layer your more moist ingredients. In the Asian salad, that’s the canned oranges and pineapple.
After that, you’ll add your salad greens and your sturdier vegetables. These are the ones you want to wait to dress until you’re serving the salad. You can decide if you want the sturdy veggies or the greens as the top layer. Either is fine, as long as both are separate from the high-moisture ingredients at the bottom of the jar.
