1 tablespoon olive oil, 1 small onion, 2 cloves garlic
Start to boil water: While onion is cooking, begin to boil water in a large pot big enough to fit your peppers. Add in a pinch of salt. Prepare a large bowl of ice cold water.
How to blanch peppers: Add peppers to boiling water and cook for 3 minutes until skin starts to soften, rotating them if they are not fully submerged.
2 large bell peppers
Submerge in ice bath: Remove peppers with tongs and immediately submerge in ice water bath for one minute to stop the cooking process. Pat dry with paper towel to remove excess water.
Carve out peppers: Cut peppers in half and carve out the inside using a small paring knife or spoon.Tip: If you have a few seeds stuck in the pepper rinse the pepper under cold water to rinse it out. Mix together stuffing ingredients: Combine barley (cooked), sliced tomatoes, chopped basil, vegan feta crumbles, salt, pepper, and Italian herbs.
2 cups barley, ½ cup cherry tomatoes, ½ cup vegan feta, ¼ cup basil
Prepare stuffed peppers: Spoon barley mixture into each pepper and press down with a spoon to fill the pepper crevices. Top peppers with more cheese if desired.
Cook peppers: Place peppers in preheated oven and cook for 15 minutes (uncovered) until peppers are tender but still slightly firm and the inside stuffing is warm. If peppers are too hard, cook for another few minutes.
Serve with more fresh basil on top if desired.
