One Pot Herbed Chicken Tagine with Split Peas

Name: One Pot Herbed Chicken Tagine with Split Peas
Ingredients: 4 chicken thighs, bone-in but skins removed; 1/2 tsp black pepper; 2 onions, roughly chopped; 1 tbsp cumin; 4 tbsp oil; 1/2 cup dried split peas; 3 tbsp tomato paste; 6 tbsp cilantro, roughly chopped and separated; 4 tbsp mint, roughly chopped and separated; 3 tbsp dried fenugreek leaves (chop them with a knife too because they tend to be kinda stringy. The chopping helps with that); 2 tsp Kashmiri chili powder (Aleppo pepper or paprika will work too); 1/2 tsp cayenne; 8 cloves garlic, roughly chopped (not minced); 3 medium carrots, cut into 1 inch thick slices; 1 tsp salt (or to taste); juice of 1 lemon
