Dice all veggies and bacon.
Cook rice and quinoa. I usually cook them separate. But cooking both together works as well. Warm up the butter on a pan.
Add onions to the pan.
Once onions are browned, add diced garlic.
Add the bacon and cook for few minutes till juices realized and crisp.
Mushrooms - add to the skillet and cook them till soft; or as on my pictures you can use another pan to do mushrooms separate.
Add all the diced vegetables, cover and simmer everything stirring occasionally till veggies are soft.
Add the mushrooms if done separately.
Season with salt and pepper.
Put the rice and quinoa in one big bowl, add everything that is in the pan to it.
Mix well and enjoy !
