Add additional seeds like chia seeds or sunflower seeds.
You can add in cooked vegetables too if you have leftovers such as peas, zucchini, leeks, asparagus, bell peppers, or onions.
Feel free add nuts for even more protein and healthy fat such as almonds, cashews, walnuts, or pecans.
You can add in fresh herbs like fresh parsley, fresh dill, basil or thyme go great with this salad.
If you want to add some carbs into this salad to make it more complete, rice, brown rice or quinoa is a great option. I love this for an energy boost if I want a little more out of this salad!
