What plant is this ?

It might be too early too tell but I was hoping someone knows what this is . I put lots of seeds in this soil (including lettuce ) 6 months ago but nothing came out . The last ones I put in were strawberry seeds but I don’t think these look like strawberry leaves at all and perhaps just some weeds that managed to get it among the soil 🙁 I picked some leaves to taste and it tastes bitter
