This was a great sandwich! I roasted the veggies in the oven at 450*F. for about 20 minutes. I didn't have rosemary oil so used extra virgin olive oil and added about a tsp. of rosemary to it. I used dark wheat sub rolls and left out the fresh basil cause I didn't have any. I put just a light coating of mayo on the bread and drizzled a little more baslamic vinegar over the veggies. Delicious! Thanks Rita!
