This is one of those recipes that makes the (relatively minimal) effort of growing fresh herbs worthwhile.
1/3 cup olive oil
3 tbsp lemon juice
3 garlic cloves, finely chopped
2 tbsp chopped fresh oregano
1 tbsp chopped fresh tarragon
2 tbsp chopped fresh parsley
1 tbsp chopped fresh thyme
1 tsp salt
ground pepper to taste
4 boneless, skinless chicken breasts
Whisk the liquids and herbs together. Pour over chicken breasts and let sit 30+ minutes. Grill. You can use just about any combination of herbs available or just one or two. Sage, chives, marjoram, rosemary, lemon thyme, pineapple sage...
And another use for those yummy herbs that can last you for several months: mix your favorites with a little lemon zest and work into soft butter. Make into logs (for easier cutting later) rolled in parchment and freeze. Great on bread, crackers (if you're not wheat-free :)), smothered on corn on the cob or, when the weather starts to cool, slices tucked under the skin of a whole turkey or chicken before roasting. The kids love this. We use Earth Balance Natural Buttery Sticks (gfcf).
