Heat olive oil in a pan and then add sliced onion and red bell pepper and sauté until onion becomes fragrant. Then add in the mushrooms and pinenuts, followed by salt and spices.
Cook for about 5 minutes and then add the spinach on top of everything along with about ¼ cup water. The spinach will begin to wilt within a minute or two.
Right when the spinach has started to wilt, add in the thoroughly rinsed black beans and chick peas. Stir a few times to mix all ingredients and then let cook for about 3 minutes.
Remove from heat and top with diced parsley. Serve while warm.
