Heat a large saucepan on medium with a bit of olive oi. The one with sides.

Add garlic, onion, carrot and mushrooms to the pan. Add all of the seasoning and s/p. Sweat until mushrooms and onions are good and soft.

Add lentils, water and veggie paste. Bring to a boil, turn down the heat and cover. Let simmer for 15-20 minutes or as long as it takes for most (not all) of the liquid to absorb and lentils to be done.

Idk if this is necessary or not, but create a lil roux with the flour and butter. I'm sure you could also use cornstarch but I didn't have any. I just used the microwave to heat these, stirring every 20/30 seconds. 1 1/2 total. Add this mixture to the pan and stir.

Cover and let simmer for another 5 minutes. Add bag of spinach, let wilt a bit and then stir.

Put a little in a bowl and let sit until cool enough to eat. If too watery let cook more, if not seasoned enough add more duh. Done.
