Oat Crumble: Preheat oven to 350 degrees F (180 degrees F). Toss together oats, olive oil, parsley, thyme, garlic powder, onion powder, paprika and salt. Spread on parchment paper-lined baking sheet. Bake, mixing occasionally, for 8 to 10 minutes or until golden and toasted. Let cool.
Mash together avocado, lemon juice and salt; spread evenly over toast. Arrange cherry tomatoes over top. Sprinkle each serving with 1 tbsp (15 mL) Oat Crumble. (Refrigerate remaining Oat Crumble in airtight container for up to 1 week.) Serve immediately.
