I substituted celery for onion. I didn't have any onion, plus my husband hates it, unless it's in salsa. I didn't add greens. I did add about 6 cherry tomatoes, split in half. I also added 1/4 tsp of nutritional yeast and 1 tbsp of pine nuts.
I served this with fresh sliced mango and a side salad and garlic toast. I'm so full.
