Put the dried polenta, water, butter, and garlic powder in a small saucepan that has a tight fitting lid. Mix together thoroughly and put on a burner over high heat with no lid yet.
Once the grits have come to a boil, stir with a spoon, reduce the heat to medium low, and put the lid all the way on the pot. Cook for 8 minutes.
In the meantime, heat a small frying pan over medium heat with 1 tsp of olive oil. Once it is heated, add in the carrots, peppers, tomatoes, and scallions. Lightly salt the vegetables.
Saute the vegetables, flipping occasionally. They should be done in about 5 minutes, but keep an eye on them so they don't burn.
Remove the vegetables from the heat. Once the polenta is done, remove it from heat as well. Add in the shredded cheese, but reserve a small handful for garnish.
Mix the cheese in and put the lid back on so the cheese can steam into the polenta.
When ready to serve, spoon the polenta in a bowl. Arrange the vegetables and and reserved cheese for garnish on top. Salt and pepper to taste.
This recipe doubles easily.
