Preheat oven to 350F and set out a 6 cup casserole dish. There's need to oil the dish.
Steam broccoli for a couple of moments to defrost. Chop into bite-size pieces and lay in the bottom of a casserole dish.
Meanwhile, saute onion, mushrooms and garlic with 1 teaspoon of oil for 5 minutes, until golden. Spread on top of the broccoli.
Add chickpeas on top, then mushroom soup, then cheese topping.
Place in the oven, uncovered, for 45 minutes.
Notes
For the cream of mushroom soup - I used homemade sunflower milk instead of almond milk, added 1 cup cauliflower to make it thicker and doubled the onion powder.
This recipe can be frozen once prepared.
