Chop the onion. Combine broth, barley, and onion in slow cooker (if using BTB, add 1.5 tsp to COLD water, remember no boiling water directly into a cold slow cooker!). Cover and cook on low 3-4 hours or until most of the liquid is absorbed.

When half the time has elapsed, add the frozen peas.

When the time has elapsed, add the lemon juice, lemon peel, and butter. Cover and cook on high 10 minutes or until heated through. Season to taste with salt and pepper.

Calories: 215 per quarter recipe. Could make a good meal prep starch if we like it. Consider serving with a little bit of parmesan atop as a treat :D

Very very filling because it's full of fiber and pretty cheap to make (since barley is cheapo). A little bland, and it might be better if it's cooked to the length of time indicated above (changed from original recipe; first go through was done to a sticky, globby tasty mess about halfway through the original cooking time!!). Definitely a keeper and good for meal prep for texture, nutrition, and fiber, even if the flavor is only a 3.5.
