Slow Cooker Sausage Lentil Soup

1 pound lentils

1 cup diced celery

1 cup diced onion

1 cup diced carrot

2 cloves garlic, chopped

1 pound sausage (we like apple chicken sausage)

6 cups chicken or veggie broth

2 cans diced tomatoes, undrained

2 cups chopped spinach or kale

Juice of 1 lemon

1 teaspoon Canadian steak seasoning (or salt and pepper to taste)

Brown the sausage then add all ingredients to crock pot and cook on high for 4-6 hours or low for 6-8 hours. Before serving, blend 2-3 cups in blender and add back in or use immersion blender to thicken.
