Roast the tomatoes and jalapeno. To do that just stick them on a skillet and burn them on all sides, set aside to cool
Chop onion, tomatoes, jalapeno and garlic very fine. (you can do bigger pieces if you like it chunky). Set aside.
Mash avocados and 1 tsp veganaise into whatever bowl you want to use.
Add tomatoes, onions, garlic and 1/2 of the jalapeno to the avocado mixture.
Mix it all up. Salt to taste. Add more of the jalapeno if you want more kick (after you taste it). Add more veganaise if you want it creamier.
