Add oil to a large sautee pan and cook garlic and onions until heated (about 3 min)

Add chicken and cook until opaque throughout

Add in mushrooms and eggplant and cook until heated through -- don't overcook these, otherwise they'll be mush by the time you're finished cooking everything.

Season well with salt and pepper

Add in your tomatoes, artichokes and olives. Once they're heated through add in you spinach in batches and mix into other veggies until wilted and mixed in.

Once everything is cooked, give it a taste test. Does it need more seasoning? Add it now. You can also mix in lemon juice or chili pepper flakes if you want more depth of flavor
