3)Place tomatoes in a single layer on a baking sheet and roast for 15-20 minutes until the soft. (Depending on the size of your tomatoes, it may take less time- check on them around 10 minutes.)
4)Remove tomatoes from oven and let cool completely.
5)Halve and pit the avocados, then place in a large bowl along with the red onion, garlic clove, lemon juice and pinch of salt and pepper. Using a fork or potato masher, gently mash the ingredients together, leaving a few chunks of avocado.
6)Add in the basil and ⅓ of the roasted tomatoes and gently fold together.
7)Spread the guacamole onto a platter or dish and top with the rest of the roasted tomatoes. Serve with vegetables, tortilla chips, pita chips or slathered on bread for yummy guacamole toast.
