Wash the baby greens and dry completely. Divide them in 2 salad plates/bowls.
Take a heavy pan and heat 1/2 tbsp. olive oil in it. Once hot, reduce the heat to medium and add onions to it. Cover and cook for 2 minutes till it becomes soft. Now cook for 1 more minute uncovered and brown lightly.
Add zucchini slices and bell peppers. Toss them and cook for another 3 minutes till the zucchini is slightly cooked. Add oregano, salt and black pepper. Toss well.
Add cherry tomatoes, balsamic vinegar and sun dried tomatoes. Toss well on high heat for few seconds and turn off the heat. Sprinkle Sumac and toss again.
Divide the warm vegetables in 2 equal parts on greens in the bowl.
Sprinkle with dried cranberries, toasted pine nuts, feta cheese and sliced olives.
