Use a heavy skillet to caramelize a finely sliced onion with 1 tbsp vegetable oil, using low temperature, 15 to 20 mins.
Drain and rinse 1 can of black beans, then add to the onions along with 1 tbsp. Penzey's salsa and pico seasoning, or similar, 1/8 tsp. cayenne, and a pinch of salt, keep warm.
Lightly coat the chicken breast with olive oil, then season all sides with your choice of chipotle style seasoning, (I used Penzey's chicken taco seasoning)
Grill chicken breast in a heavy skillet or cast iron grill pan on high heat, smooth side down for 2 minutes.
Turn the chicken over, lower the heat to low, cover the skillet for 6 to 8 minutes until the internal temperature is at least 140°, remove to a plate then rest the chicken 5 minutes covered before slicing.
Assemble the ingredients in a bowl first putting the romaine on the bottom, mixing in some chopped cilantro.
Put the beans on top of the lettuce, then add the sliced grilled chicken breast, the yogurt and salsa, then garnish with chopped green onion, more cilantro, and a few halved grape tomatoes.
Serve warm
Notes
To caramelize the onion, start with 1 tablespoon of vegetable oil in a skillet on low to medium-low heat. Add the sliced onions with a pinch of salt and cook while occasionally stirring until the onion is a light brown color. This may take 15 to 20 minutes.
You can make your own Chipotle-style seasoning with 1 tbsp. chili powder, 1 tbsp. sweet paprika, 1 tsp. garlic powder, 1 tsp. ground cumin, 1 tsp. dry oregano, 1/2 tsp. coarse salt, and 1/4 tsp. cayenne pepper.
Store leftover ingredients separately in an airtight container for up to 4 days refrigerated.
Nutrition information is for one burrito bowl using the ingredients in the recipe card. Brown rice is a good addition to the bowl and would add about 110 calories per 1/2 cup. Season the rice with additional Chipotle style seasoning and lime juice for flavor.
