Preheat your oven to 425 F.
Peel and cube the sweet potato. Toss with olive oil, salt, pepper and paprika. Spread evenly on a baking sheet lined with parchment paper. Bake for 15 minutes, flipping halfway through baking time.
While the potatoes are baking, assemble the other ingredients. Rinse the arugula and cucumber, slice tomatoes and assemble your grains if you’re using them.
After 15 minutes of baking, add the frozen falafels to the baking sheet with sweet potatoes. Bake for another 8-10 minutes until golden brown.
Assemble the cava bowl. Start with the grains, then layer with the sweet potatoes, falafels and veggies. Top with hummus and tzatziki and a dressing of your choice.
Enjoy warm or let cool before storing in an airtight container for up to 4 days.
