Looking for a hearty, satisfying vegetarian sandwich?  My favorite veggie sandwiches feature either grilled portobello or grilled eggplant, both of which have a meaty robustness.  Trader Joe's carries a product in the freezer section called "Misto Alla Griglia," marinated grilled eggplant and zucchini, which takes the work out of enjoying these grilled veggies.  I used them in a sandwich here, but they're perfect for serving alongside an arugula salad or incorporating into a lasagna (grab some TJ's pasta sauce and no-boil noodles, and that lasagna really can't get any easier.)

In this sandwich, the rich eggplant and zucchini slices contrast nicely with some fresh, peppery arugula and tangy feta.  Don't skip the lemon garlic sauce - it adds so much flavor and brings it all together.  If you're not crazy about garlic, start with a little less and see how you like it.  We all mmm-ed and aah-ed as we ate these sandwiches, so I hope you love it too!

Grilled Veggie Sandwich with Lemon Garlic Sauce
1 bag frozen Misto Alla Griglia (Marinated Grilled Eggplant & Zucchini)
Petits Pains Rustiques (4 Country Style French Rolls)
Fresh arugula (a few handfuls)
Crumbled Feta with Mediterranean Herbs

Lemon Garlic Sauce (enough for 4 sandwiches)
4 Tbsp mayo
4 tsp lemon juice
4 cubes frozen Crushed Garlic (or 3-4 small cloves garlic, crushed)

1) Thaw bag of eggplant overnight in fridge, or microwave until warm per package instructions.
2.) Cut rolls in half.
3.) In a small bowl, stir together the ingredients for the Lemon Garlic Sauce until smooth. 
4.) Build the sandwiches by drizzling a bit of the sauce into the bottom half of each roll.   Add a big handful of arugula, then 1/4 of the warmed eggplant and zucchini slices, and finish with a topping of feta. 

Serves 4. 
To make just one sandwich: use one roll, a handful of arugula, 1/4 of the veggies, and for the sauce use 1 Tbsp mayo, 1 tsp lemon, and 1 clove/cube garlic.
