Easy recipe: Instant pot eggplant and carrots curry

So I ran across this recipe and thought it would be great as eggplants are difficult for me to cook on the stove. I tend to either overcook or undercooked them when I do eggplant curry on the stove so figure out an easy way to cook them in the instant pot when I saw this recipe:

Here's my easy version of it:

Ingredients:
1 whole onion - chopped
2 long eggplants or 1 if you have the bigger thicker ones - cubed
2 small carrots or a bag if they're the snack bags - cubed or thinly sliced
2 cans of coconut milk
2 cubes of the curry spices or you can make your own from the receipt linked above
4 cups of water (or 4 in the cans of the coconut milk)

Optional:
3 tomatoes
basil
tofu or any meat on hand

Instant pot
You can do the saute steps like in the recipe linked above or you can just put in all the ingredients and press the soup option like I do.
