Grill the salmon following the directions in this post. You may wish to omit the glaze and just use the salad dressing. Keep warm by wrapping in foil.
MAKE THE CROUTONS: Slice the bread into 1" cubes. Drizzle the olive oil in a non-stick skillet. Add the bread cubes and sprinkle with the seasonings. Cook over medium heat until the outsides are golden brown.
Layer the spinach, peppers, salmon, feta cheese and croutons on a plate.
Top with balsamic vinaigrette.
Notes
You can use whatever veggies you want on this salad. We have had it with cherry tomatoes, olives, shredded carrots etc. It is very adaptable. I usually omit the glaze when grilling the salmon for this salad because the dressing is so good. The Trader Joe's balsamic vinaigrette is amazing. Our favorite dressing!
