Here is a recipe I found on the net and I hear it comes extremely close to the bread macaroni grill uses. I have not tried it yet but I plan to.

Macaroni Grill Bread
Yield: 2 loaves

1 tbsp. dry yeast
1 tbsp. sugar
1 cup warm water (105-115F)
2 1/2 cups all purpose flour
1 tsp. salt
2 tbsp. fresh minced rosemary
1 tbsp. olive oil
nonstick cooking spray
2 tbsp. butter

Place yeast, sugar and water in large bowl or food processor and allow mixture to become bubbly.

Mix in 2 cups of flour and the salt. Add one tablespoon of the fresh chopped rosemary. Knead for about 10 minutes by hand or in food processor about 30 seconds until smooth and elastic. add flour if necessary.

Oil a bowl, put dough in it and cover with a towel. Let dough rise in a warm place for one hour until doubled.

Punch down dough and divide in half. Let dough rest about 5-10 minutes.

Spray baking pan or cookie sheet with cooking spray. Shape the dough into 2 small rounded oval loaves.

Melt margarine or butter. Brush over the top of the loaves. Sprinkle remaining 1 Tabelspoon of rosemary over the loaves and press lightly into the surface. Let loaves rise again until doubled, about 45 minutes.

Preheat oven to 450 degrees F. Lightly sprinkle course salt over the loaves. Bake for 20-25 minutes, until lightly browned.
