In a skillet over medium-high heat, sauté veggies with cooking spray for a couple minutes. Add to the bottom of a slow cooker.
Spray skillet once again with cooking spray and add ground meat. Cook until browned and add to slow cooker. Add seasonings and stir to mix.
Add chicken broth and cheese cubes. Stir and cook on low for 4 hours. Serve with pickles slices if desired.
Instant Pot
Turn IP to saute function. Add 1 tsp olive oil and saute veggies for a couple minutes until softened.
Add ground meat. Cook until browned. Drain and add seasonings. Add chicken broth and cheese cubes. Place lid on the cooker and close vent to sealing position. Select high pressure for 5 minutes. Allow natural release for 10 minutes.
Move vent to venting position and stand back, allowing steam to release if needed. Use slotted spoon to scoop into bowls (avoiding liquid helps keep the meal solid and maintain better fullness and portion control). Serve with pickles slices if desired.
