Combine all marinade/dressing ingredients into a liquid measuring cup with a pour spout and whisk together until combined.
Add 1/3 of the marinade/dressing mixture to a bowl with the chicken and toss to evenly coat. Add 1 tablespoon of the marinade dressing mixture over the halved cherry tomatoes.
Heat a 12" high sided skillet or everyday pan over medium high heat.
Cook chicken until cooked through to 165°F. Remove from pan and set aside.
Add the cherry tomato halves to the same pan and cook for 30-60 seconds, until the skins are blistered and charred. Remove from the pan and set aside with the chicken.
Add the water to the skillet to deglaze the pan. Use the wooden spoon to loosen the bits on the bottom of the skillet. Bring to a boil.
Add the lentils to the water, bring up to a boil, then reduce to a simmer. Cook Lentils from 10-15 minutes until the water is absorbed and lentils are tender.
While the lentils are cooking, chop the chicken into bite sized pieces, prep your goat cheese, and chop the scallion.
Once the water has been absorbed into the lentils, turn off the heat and add the remaining dressing/marinade, chicken and tomatoes and stir to combine evenly with the lentils. Sprinkle with the crumbled goat cheese and scallion.
Serve right from the pan or divide into 4 meal prep containers. Can be served warm or cold.
