Step 1

In a 12-inch nonstick skillet over medium heat, melt the butter and add the onion, sugar and 1/4 teaspoon salt. Cook until the onion is softened, about 2 minutes. Stir in the garlic and cook until fragrant, about 30 seconds.

Step 2

Stir in the peas and thyme and cook, stirring often, until the peas are just heated through, about 3 minutes. Season with black pepper (and additional salt if desired) and serve immediately.
