Preheat the oven to 425 degrees.
In a mixing bowl, add the garlic, tomato, jalapeño, onion, cilantro, and lime juice. Season with salt and stir to combine. Allow the mixture to chill in the fridge until ready to serve.
Place sliced bread onto large baking sheet. Brush with olive oil and bake 8 minutes, or until crusty and golden brown.
Remove the bread from the oven and allow to cool slightly. Then, spread each piece of toast with the mashed avocado and season with salt.
When ready to serve, spoon the tomato mixture over each slice of bread.
Serve immediately.
