In a medium sized skillet, heat oil on medium high. Saute onions and bell peppers until soft and translucent. Add the garlic and cook until fragrant, about thirty seconds, dont let it burn! Add the reserved flowers and saute until warmed through, about 3 minutes. Season with cumin, cayenne, salt and pepper. Add Chopped cilantro and remove from the heat.
Grease a large skillet with cooking spray and set to medium heat. Lay a tortilla down and on one half, add 2 slices of cheese. Top with Hibiscus mixture and 2 more slices of cheese. Fold empty half over and cook until cheese is melted and tortilla has browned and is crisp! ( lower the heat if needed to let the cheese melt)
Remove from the pan and cut into 2 or four pieces. Repeat with the other tortilla and serve with lime wedges, avocados, and sour cream.
