I've been doing a really nice broccoli soup for the Instantpot myself.
1 onion, sauteed in Instantpot
4 cloves of garlic, same
1/2 head of cauliflower
2-3 heads of broccoli
1 large potato or equivalent small potatoes
4 1/2 cups of vegetable broth
1 tsp oregano
1 tsp salt
Instantpot ten minutes, food process to have a thick consistency, throw as much cheese in as your heart desires and a dab of milk.
I would love to try the sausage one! Looks yum yum!
