While the grits are simmering on the stove, heat the olive oil in a frying pan until hot. Add the bacon and fry until it starts to brown.
Add the onions and bell pepper and fry until it gets begins to soften.
Add mushrooms and cherry tomatoes and fry until they are soft and cooked.
Remove vegetables in a bowl. Add shrimp to the frying pan. Be careful not to overcrowd the pan.
Fry the shrimp just until it turns pink. Do not overcook the shrimp otherwise it is tough. If you need to do these in batches, take out the cooked shrimp and add to the vegetables.
After all of the shrimp is cooked, take all vegetables and shrimp and vegetables and add back to the frying pan for 1 minute until it is warmed. You can mix in some of your favorite hot sauce if you like it spicier.
Divide the grits on individual serving plates. Top with shrimp and vegetables. Sprinkle the green onion over the top. Enjoy!
