1Thaw the imitation crab if it is frozen and set aside.
In a large pan, melt the butter over medium heat.
Add the chopped onion and minced garlic to the pan and sauté until the onion becomes translucent.
Dice the yellow pepper and add it to the pan, cooking for another 2-3 minutes.
Stir in the arborio rice, ensuring it is well coated with the butter and vegetables.
Gradually add the chicken broth, one cup at a time, stirring frequently and allowing the liquid to be absorbed before adding more.
Continue this process until the rice is creamy and cooked to your desired texture, about 18-20 minutes.
Gently fold in the imitation crab and parmesan cheese, stirring until the crab is heated through and the cheese is melted.
Season with salt and pepper to taste, and serve hot.
