Grilled Chicken Caesar Salad Sandwiches

Boy, is it just me or is that really long? Anyway, this is kind of semi-homemade. My husband loves chicken Caesar but it doesn't really fill him up. So I thought I'd make sandwiches, using cheesy garlic bread. Sounds nom, right? Not, I wanted to marinate the chicken but I didn't really think the creamy Caesar dressing would work well. So I opened her up and sniffed it and then concocted a marinade. So these measurements are very approximate.

4 boneless, skinless chicken breast halves
EVOO
2-4 cloves chopped garlic
salt
cracked black pepper
1/4 cup or so of red wine vinegar (lemon juice would also be good, or a combination of the two)`
1/2-1 tsp dry mustard
1/4-1/2 tsp cumin
1 tbsp dried thyme, crushed
2-3 tsp onion powder
3 romaine hearts
Caesar dressing (I like Kraft.)
1-2 loaves frozen Pepperidge Farm garlic bread. I like the five cheese.

Whisk together everything between EVOO and the onion powder. Pour over the trimmed up chicken breasts in a gallon sized Ziploc bag and stick it in the fridge for a day or two. It helps if you stab a few holes in the chicken breasts (and it's fun too.) Also, put the bag in a big bowl so it doesn't leak chicken juice all over teh bottom of your fridge.
Preheat your oven to 375.
Preheat a grill pan over medium-high heat. If you use cast iron, it'll infuse some extra iron into your food! Just a lil tidbit. Make sure your grill is good and hot so you get those nice lines. Then, transfer your chicken titties to an oven-safe pan (I used a cast-iron skillet that's older than I am,) stick a meat thermometer in there that'll go off when the chicken gets to 175-180*. When the timer goes off, take teh chicken out to rest a bit and turn the oven up to 400. Put the bread in.
Wash the romaine and cut it up for the salad, and toss with the dressing in a big bowl. Now, I stopped here, cut up my chicken, and served the salad with the bread on the side. But you could also toast the bread for just a minute or two longer and then make giant, delicious sammitches. The choice is yours. Let me know if you try out this recipe!
