Mexican Tostadas with Cashew Sour Cream

by | Jan 19, 2018 | Entrees, Favorites | 0 comments

There’s a Mexican restaurant close to our apartment that makes THE.BEST (!) tostadas. A tostada is just an open face hard shell taco loaded with grilled veggies, cheese, sour cream, and guacamole. It’s so delicious but so high in calories – yikes!

So, we decided to FLIP tostadas at home and this is how we did it. Oh, we FLIPPED sour cream too. Get excited because it’s A-mazing! 🙂


2 green squash, halved lengthwise, cut into 1/2- inch slices

4 cups shiitake mushrooms, sliced

1 small yellow onion, chopped

2 small garlic cloves, minced

2 teaspoons organic taco seasoning mix

1 ripe avocado, halved, cut into squares

Olive oil

1 lime cut into wedges

¼ cup fresh cilantro, chopped

Salt and fresh pepper to taste

Cashew sour cream (recipe below)

100% yellow corn tostadas for serving


Preheat the oven to 425°F. Evenly coat the green squash slices with olive oil, salt and pepper to taste. Spread onto a baking sheet and roast, 25-30 min. or until tender. Remove from the oven and set aside. Place a pan or skillet over medium heat and drizzle with olive oil. Once hot, add garlic and onions and cook until onions become translucent, 2-3 min. Add mushrooms, taco seasoning, salt and fresh pepper to taste, combine and cook, 10-15 min or until mushrooms are tender and browned. Add the cooked green squash and mix well. Pile cooked veggies onto the corn tostadas. Top with avocado, cilantro, cashew sour cream and a squeeze of fresh lime juice. Garnish with lime wedges. Serve and Enjoy!
